Inverse Operations
When moving a term to the other side of an equation, the operation is inversed.Distributive Property
aa(b+c)=(b+c)=aab+b+aaccTo solve for mm, it needs to be alone on one side.Start by expanding the left side of the equation by using the Distributive Property.77((mm +2)++2)+22(6-2(6−2mm)) == 44mm 77mm ++77(2)+(2)+22(6)+(6)+22(-2(−2mm)) == 44mm 77mm +14+12-4+14+12−4mm == 44mm 33mm +26+26 == 44mm Next, move 3m3m to the other side by subtracting 3m3m from both sides of the equation.33mm +26+26 == 44mm 33mm +26+26 -3m−3m == 44mm -3m−3m 2626 == mm 3m-3m3m−3m cancels out mm == 2626 Check our workTo confirm our answer, substitute m=26m=26 to the original equation.7(m+2)+2(6-2m)7(m+2)+2(6−2m) == 4m4m 7(26+2)+2(6-2(26))7(26+2)+2(6−2(26)) == 4(26)4(26) Substitute m=26m=26 7(28)+2(6-52)7(28)+2(6−52) == 104104 196+2(-46)196+2(−46) == 104104 196-92196−92 == 104104 104104 == 104104 Since the equation is true, the answer is correct.m=26m=26 -

Inverse Operations
When moving a term to the other side of an equation, the operation is inversed.Distributive Property
aa(b+c)=(b+c)=aab+b+aaccGet yy alone to the left side and all constants to the right.Start by expanding both sides of the equation by using the Distributive Property.22((yy +3)++3)+ 55((yy +2)+2) == 44(9-4(9−4yy)-)− 3(16-3y) 2y+ 2(3)+ 5y+ 5(2) = 4(9)- 4(4y)- 3(16)- 3(-3y) 2y +6+5y+10 = 36-16y -48+9y 7y +16 = -7y -12 Next, move 16 to the other side by subtracting 16 from both sides of the equation.7y +16 = -7y -12 7y +16 -16 = -7y -12 -16 7y = -7y -28 16-16 cancels out Then, move -7y to the other side by adding 7y to both sides of the equation.7y = -7y -28 7y +7y = -7y -28 +7y 14y = -28 -7y+7y cancels out Finally, remove 14 by dividing both sides of the equation by 14.14y = -28 14y÷14 = -28÷14 y = -2 14÷14 cancels out Check our workTo confirm our answer, substitute y=-2 to the original equation.2(y+3)+5(y+2) = 4(9-4y)-3(16-3y) 2(-2+3)+5(-2+2) = 4(9-4(-2))-3(16-3(-2)) Substitute y=-2 2(1)+5(0) = 4(9+8)-3(16+6) 2+0 = 4(17)-3(22) 2 = 68-66 2 = 2 Since the equation is true, the answer is correct.y=-2 -

To solve for x, get x by itselfDistribute the value inside the parenthesis.6(x+2)-4(x-1) = 20 6(x+2) = (x×6)+(2×6) = 6x+12 -4(x-1) = (x×(-4))+(-1×(-4)) = -4x+4 (6x+12)+(-4x+4) = 20 2x+16 = 20 Subtract 16 from both sides of the equation2x+16 -16 = 20 -16 2x+16 -16 = 20 -16 16-16 cancels out 2x = 4 2x÷2 = 4÷2 Divide both sides by 2 2x÷2 = 4÷2 ×2÷2 cancels out x = 2 x=2 -
Question 4 of 5
4. Question
Solve for v-8v+7(v+8)=32-7v- v= (-4)
Correct
Well Done
Incorrect
To solve for v, get v by itselfDistribute the value inside the parenthesis.-8v+7(v+8) = 32-7v -8v+((v×7)+(8×7)) = 32-7v -8v+7v+56 = 32-7v -v+56 = 32-7v Get the v variable on one side of the equation-v+56 +7v = 32-7v +7v Add 7v to both sides -v+56 +7v = 32-7v +7v -7v+7v cancels out 6v+56 = 32 6v+56 -56 = 32 -56 Subtract 56 from both sides 6v+56 -56 = 32 -56 56-56 cancels out 6v = -24 6v÷6 = -24÷6 Divide both sides by 6 6v÷6 = -24÷6 ×6÷6 cancels out v = -4 v=-4 -
Question 5 of 5
5. Question
Solve for k11-5k=4+7(1-5k)- k= (0)
Correct
Well Done!
Incorrect
To solve for k, get k by itselfDistribute the value inside the parenthesis.11-5k = 4+7(1-5k) 11-5k = 4+((1×7)+(-5k×7)) 11-5k = 4+7-35k 11-5k = 11-35k Get the k variable on one side of the equation11-5k +5k = 11-35k +5k Add 5k to both sides 11-5k +5k = 11-35k +5k -5k+5k cancels out 11 = 11-30k 11 -11 = 11-30k -11 Subtract 11 from both sides 11 -11 = 11-30k -11 11-11 cancels out on both sides 0 = -30k 0÷(-30) = 30k÷(-30) Divide both sides by -30 0÷(-30) = 30k÷(-30) ×(-30)÷(-30) cancels out 0 = k k = 0 k=0
