How do you work out the problem -9 plus 7x equals -37?

Answer 1

simple. Set out the problem clearly:

-9 + 7x = -37.

Move the singular number over the equals sign, which makes itself opposite, in this case, the 9 is negative, and when moved over the equals sign, becomes positive.

7x= -37+9

7x= -28

x= -28/7

x = -4
