Question

PLEASE HELP!!!

Write a simplified equation to solve for X.

Using the equation, solve for x

Answer 1

x=40

Explanation:

2x+100=180

2x=180-100

2x=80

x=40

Answer 2

x = 40

Explanation:

x + 100 + x = 180 {Straight line angles}

2x + 100 = 180 {subtract 100 from both sides}

2x = 180 - 100

2x = 80 {Divide both sides by 2)

x = 80/2

x = 40
