Question

What is the value of x?

Answer 1

20

Explanation:

3x+50=6x-10 (vertically opposite angles)

50+10=6x-3x

60=3x

60/3=x

x=20

Answer 2

x = 20

Explanation:

6x - 10 = 3x + 50 {Vertically opposite angles}

6x = 3x + 50 + 10 {Combine like terms}

6x = 3x + 60 {Subtract 3x from both sides}

6x -3x = 60

3x = 60 {Divide both sides by 3}

x = 60/3

x = 20
