Setting Up One Step Equations Using Addition or Subtraction

9 + t = 56

• -47

• 47

• -65

• 65

In the equation
x + 7 = 12
7 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation? 

• Subtract 7 from both sides. The solution is x = 5.

• Add 7 to both sides.
  The solution is x = 19.

• Multiply both sides by 7 The solution is x = 84.

y + 6 = 20

• y = 22

• y = 13

• y = 14

• y = 16

x - 10 = 12

• 22

• -22

• 2

• -2

x - 62 = 123

• add 62 to each side

• multiply each side by 62

• subtract 62 from each side

• Add 123 to each side

• Add 5 to both sides

• Subtract 8 from both sides

• Subtract 5 from both sides

• Divide both sides by 5

To Solve the Equation Below, you'd
x - 62 = 123

• add 62 to each side

• subtract 62 from each side

• multiply each side by 62

• Add 123 to each side

What would be the first step in solving this equation?

• subtract -10 to both sides

• subtract 20 to both sides

• add 20 to both sides

• add -10 to both sides

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

• 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?
-3=x+5

• add 3 to both sides

• subtract 5 from both sides

• add 5 to both sides

• subtract -5 from both sides
