Question

Solve for x. 7x/3 + 2 = -15


A. -119/3
B. -91/3
C. -51/7
D. -39/7​

Answer 1

C. -51/7=-7.28

Explanation:

Isolate x on one side of the equation.

7x/3+2=-15

7x/3+2-2=-15-2 (First, subtract 2 from both sides.)

-15-2 (Solve.)

-15-2=-17

7x/3=-17

3*7x/3=3(-17) (Next, multiply 3 from both sides.)

3(-17) (Solve.)

3(-17)=-51

7x=-51

7x/7=-51/7 (Then, divide by 7 from both sides.)

-51/7 (Solve.)

-51/7=-7.28

x=-51/7=-7.28

So, the final answer is (C.) x=-51/7=-7.28.
