Answer:
x = -7
Step-by-step explanation:
-6x + 3 = 45
First, we need to get rid of the 3 by subtracting it by 3. We need to do the same to the number on the other side.
-6x + 3 = 45
-3 - 3
-<em>6x = 42</em>
Then, to iolate the x, we need to divide -6 by itself to cancel the number out and get x alone. We also need to divide 42 by -6 as well.

42 divided by -6 is -7.
