Question

Which of the following equations correctly represents the set-up to solve for x?

A: x-6+2x=10
B: x-6+2x=90
C: x-6=2x-8
D: x-6+2x-8=180

Answer 1

x-6 + 2x-8 = 10

Explanation:

ST + TU = SU

x-6 + 2x-8 = 10

Combine like terms

3x - 14 = 10

Add 14 to each side

3x-14+14 = 10+14

3x = 24
