Equations

Which equation(s) have x = 5 as a solution?

• x + 15 = 20

• 14x = 70

• x - 5 = 10

• x - 7.3 = 2.3

• x + 2.3 = 7.3

x + 34 = 76 ... Solve for x. (type only the number)

13x = 78 ... Solve for x. (type only the number)

What is the first step to solving this equation?

• add -8 to both sides

• subtract -8 to both sides

• Multiply -8 to both sides

• divide -8 to both sides

Which equation has w = 8 as the solution?

• 8w= 64
• 16w = 240
• 16 - w = 9
• 4 + w = 10

• 36

• -36

• 4

• -4

What would be the best first step to solving the equation?
-6x=-24

• multiply both sides by -6
