Question

Solve for x: 2x+156 4x+192

Answer 1

x = -18

Explanation:

The angles are vertical angles, so they are equal

2x+156 =4x+192

Subtract 2x from each side

2x-2x+156 =4x-2x+192

156 = 2x+192

Subtract 192 from each side

156-192 = 2x

-36 = 2x

Divide each side by 2

-36/2 = 2x/2

-18 = x
