Answer:
Step-by-step explanation:
To solve this problem, first, you have to isolate by the x from one side of the equation.
Multiply by 7 from both sides of an equation.
x/7=-8
[tex]\sf\dfrac{7x}{7}=7(-8)[/tex]
Solve.
7(-8)=-56
[tex]\large\boxed{x=-56}[/tex]
Therefore, the correct answer is d. x=-56.
