Question

Multi-step Equations
12) -(7 - 4x) = 9

Answer 1

So if you rewrite the equation it’s like -1*(7-4x)
So you do -1*7 which is -7 and -1*-4x, which is 4x. So you then have -7+4x. Then you add 7 to both sides, getting 4x equals 16. You divide both by 4, making x=4
X=4

Answer 2

4

Explanation:

-7+4x=9

4x=16

x=4
