Answer:
<h3>C. -51/7=-7.28</h3>
Step-by-step 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.
