Question 1 of 5
1. Question
Solve`y-30=55`- `y=` (85)
Hint
Help VideoCorrect
Keep Going!
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 `30` to the other side by adding `30` to both sides of the equation.`y` `-30` `=` `55` `y` `-30` `+30` `=` `55` `+30` `y` `=` `85` `-30+30` cancels out Check our workTo confirm our answer, substitute `y=85` to the original equation.`y-30` `=` `55` `85-30` `=` `55` Substitute `y=85` `55` `=` `55` Since the equation is true, the answer is correct.`y=85` -
Question 2 of 5
2. Question
Solve`26-s=2`- `s=` (24)
Hint
Help VideoCorrect
Correct!
Incorrect
Inverse Operations
When moving a term to the other side of an equation, the operation is inversed.First, make sure that the variable is positive by adding `s` to both sides of the equation.`26-``s` `=` `2` `26-``s` `+s` `=` `2` `+s` `26` `=` `2+``s` `-s+s` cancels out Now, to solve for `s`, it needs to be alone on one side.Move `2` to the other side by subtracting `2` from both sides of the equation.`26` `=` `2+``s` `26` `-2` `=` `2+``s` `-2` `24` `=` `s` `2-2` cancels out `s` `=` `24` Check our workTo confirm our answer, substitute `s=24` to the original equation.`26-s` `=` `2` `26-24` `=` `2` Substitute `s=24` `2` `=` `2` Since the equation is true, the answer is correct.`s=24` -
Question 3 of 5
3. Question
Solve`n+5=-8`- `n=` (-13)
Hint
Help VideoCorrect
Great Work!
Incorrect
Inverse Operations
When moving a term to the other side of an equation, the operation is inversed.To solve for `n`, it needs to be alone on one side.Move `5` to the other side by subtracting `5` from both sides of the equation.`n` `+5` `=` `-8` `n` `+5` `-5` `=` `-8` `-5` `n` `=` `-13` `5-5` cancels out Check our workTo confirm our answer, substitute `n=-13` to the original equation.`n+5` `=` `-8` `-13+5` `=` `-8` Substitute `n=-13` `-8` `=` `-8` Since the equation is true, the answer is correct.`n=-13` -
Question 4 of 5
4. Question
Solve for `x``x-4=10`- `x=` (14)
Hint
Help VideoCorrect
Nice Job!
Incorrect
Isolate the `x` variable on one side of the equation`x-4` `+4` `=` `10` `+4` Add `4` to both sides `x``-4` `+4` `=` `10` `+4` `-4+4` cancels out `x` `=` `14` `x=14` -
Question 5 of 5
5. Question
Solve for `a``a-30=100`- `a=` (130)
Hint
Help VideoCorrect
Fantastic!
Incorrect
Isolate the `a` variable on one side of the equation`a-30` `+30` `=` `100` `+30` Add `30` to both sides `a``-30` `+30` `=` `100` `+30` `-30+30` cancels out `a` `=` `130` `a=130`
