Solve for x.

What equation can we use to solve?

• 50 + 60 + 5x = 160

• 60 + 60 + 5x = 180

• 60 + 6x = 180

• 60 + 6x = 360

60 + 60 + 5x = 180

solve for x

• x = 12

• x = 14

• x = 120

• x = 60

Angle A says it's 10x + 24

Angle B is 6x + 72

How would you set up to solve for x?

• 10x + 24 = 6x + 72

• 10x + 24 + 6x + 72 = 180

• 10x + 24 - ( 6x + 72) = 180

• 10x + 24 = -6x - 72

10x + 24 = 6x + 72

solve for x

• x = 12

• x = 14

• x = 2

• x = 48
