Question 1 of 5
1. Question
Solve`7+y=20`- `y=` (13)
Hint
Help VideoCorrect
Excellent!
Incorrect
Inverse Operations
When moving a term to the other side of an equation, the operation is inversed.To solve for `y`, it needs to be alone on one side.Move `7` to the other side by subtracting `7` from both sides of the equation.`7+` `y` `=` `20` `7+` `y` `-7` `=` `20` `-7` `y` `=` `13` `7-7` cancels out Check our workTo confirm our answer, substitute `y=13` to the original equation.`7+y` `=` `20` `7+13` `=` `20` Substitute `y=13` `20` `=` `20` Since the equation is true, the answer is correct.`y=13` -
Question 2 of 5
2. Question
Solve`a-4=11`- `a=` (15)
Hint
Help VideoCorrect
Fantastic!
Incorrect
Inverse Operations
When moving a term to the other side of an equation, the operation is inversed.To solve for `a`, it needs to be alone on one side.Move `4` to the other side by adding `4` to both sides of the equation.`a` `-4` `=` `11` `a` `-4` `+4` `=` `11` `+4` `a` `=` `15` `-4+4` cancels out Check our workTo confirm our answer, substitute `a=15` to the original equation.`a-4` `=` `11` `15-4` `=` `11` Substitute `a=15` `11` `=` `11` Since the equation is true, the answer is correct.`a=15` -
Question 3 of 5
3. Question
Solve for `m``m+5=15`- `m=` (10)
Hint
Help VideoCorrect
Correct!
Incorrect
Isolate the `m` variable on one side of the equation`m+5` `-5` `=` `15` `-5` Subtract `5` from both sides `m``+5` `-5` `=` `15` `-5` `5-5` cancels out `m` `=` `10` `m=10` -
Question 4 of 5
4. Question
Solve for `x``x+12=16`- `x=` (4)
Hint
Help VideoCorrect
Excellent!
Incorrect
Isolate the `x` variable on one side of the equation`x+12` `-12` `=` `16` `-12` Subtract `12` from both sides `x``+12` `-12` `=` `16` `-12` `12-12` cancels out `x` `=` `4` `x=4` -
Question 5 of 5
5. Question
Solve for `y``y-3=9`- `y=` (12)
Hint
Help VideoCorrect
Nice Job!
Incorrect
Isolate the `y` variable on one side of the equation`y-3` `+3` `=` `9` `+3` Add `3` to both sides `y``-3` `+3` `=` `9` `+3` `-3+3` cancels out `y` `=` `12` `y=12`
