Question

How do I solve the equation 1/7(x+21)=-6

Answer 1

There are several ways to do it.
Here is one way:

1/7 (x + 21) = -6

Multiply each side by 7 : x + 21 = -42

Subtract 21 from each side : x = -63

Answer 2

`(1)/(7)(x+21)=-6 \\\\(x+21)/(7)=-6 \\\\ x+21=(-6)*7 \\\\ x+21=-42 \\\\ x=-42-21 \\\\ \boxed{x=-63}`
