Solve 2g - 4 = 6.

• g = 5

• g = 4

• g = 6

• g = 3

• m = 1

• m = -2

Match the following equations with their solutions.

• x = -3

• x = -10

• x = 10

• x = 3

The solution to the equation 5x - 2 = 3x + 4 is x = (a)   .

• x = 1
• x = -3
• x = -1
• x = 3

Match the following absolute value solutions with their equations.

• |2x - 5| = -21

• The solution is x = 13 or x = -23

• |x + 5| = 18

• The solution is x = 0.

• |2x| -9 = -7

• The solution is x = 1 or x = -1

• |3x| = 0

• No solution because the absolute value cannot be negative.

• x = 10
• x = 0
• x = -10
• No solution
