One Step Equations (Review pt 1)

 $x+5=12$  
What is the first step to solving this equation?

• add 5 to both sides

• subtract 5 from both sides

• add 12 to both sides

• subtract 12 from both sides

 $w-5\ =\ 3$  

• w = 2

• w = -8

• w =-2

• w = 8

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

• multiply both sides by 3

• multiply both sides by 4

• divide both sides by 3

• divide both sides by 4

Which equation has x = 5 as the solution?

• x + 15 = 10
• 2x = 5
• 2x = 10

In the equation, x + 7 = 12

7 is being added to x. How should you show your work to get the variable by itself 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.
