Answer:

x=-5

Explanation:

To solve for x, we have to get x by itself. Perform the opposite of what is being done to the equation, to both sides.

5x-7= -32

First, move all the constants to the same side. 7 is being subtracted, so add 7 to both sides.

5x-7= -32+7

5x= -32+7

5x= -25

Now, 5 and x are being multiplied. Divide both sides by 5.

5x/5= -25/5

x= -25/5

x= -5

If we want to check our answer, substitute our solution back in for x.

5x-7=-32

Substitute -5 in for x

5(-5)-7 = -32

-25-7 = -32

-32 = -32

This is true, so x is equal to -5
