Question

9x-7=-7 what does x equal

Answer 1

Answer:

x = 0

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.

First, add 7 to both sides:

9x - 7 (+7) = - 7 (+7)

9x = -7 + 7

9x = 0

Next, divide 9 from both sides:

(9x)/9 = (0)/9

x = 0/9 = 0

x = 0 is your answer.
