One Variable Equations

What is the correct step to solve for the variable?
15 = m - 5

• add 15 to both sides

• add 5 to both sides

• subtract 15 from both sides

• subtract 5 from both sides

y - 14 = 66

• 80

• 52

• 79

• Answer Not Given

x ÷ 2 = 12

• x = 24

• x = 6

• x = 20

• x = 10

Choose an expression that is equivalent to the following
6n + 2(3 - 5n)

• n + 6

• 6 - 4n

• 16n + 6

0.1( x - 20 ) > 2

• x > 40

• x < 40

• x > 220

• -3m + 36
• -9m + 36
• 3m + 36

Which expression is equivalent to (s - 12) / 2

• s/2 -12

• s - 6

• s/2 - 6

- 3( 4 - 2x) = 6

• x = 1

• x = -3 

• x = 3

What would be the best first step to solving the equation?
-3=x+5

• add 3 to both sides

• subtract 5 from both sides

• add 5 to both sides

• subtract -5 from both sides

What would be the best first step to solving the equation in one step?

• multiply both sides by 3

• multiply both sides by -3

• divide both sides by -3

• add 3 to each side
