Question

Solve for x: 3(x + 1) = −2(x − 1) + 6

A. 1

B. 4

C. 5

D. 25

Answer 1

3(x+1)=-2(x-1)+6
3x+3=-2x+8
5x=5
x=1

Thus, A would be the answer.

Answer 2

Correct option is:

A. 1

Explanation:

3(x + 1) = −2(x − 1) + 6

⇒ 3x+3= -2x+2+6

⇒ 3x+3= -2x+8

⇒ 3x+2x=8-3

⇒ 5x=5

dividing both sides by 5

⇒ x=1

Hence, the correct option is:

A. 1
