Question

Solve for x in this equation below

Answer 1

x = -20

Explanation:

• are opposite angles, therefore equal

6x + 238 = 3x + 178

3x = 178 - 238

3x = -60

x = -60 : 3

x = -20

-------------------------------------

• check

6(-20) + 238 = 3(-20) + 178

-120 + 238 = -60 + 178

118 = 118

• the answer is good
