Answer:
<u>x = 3</u>
Step-by-step explanation:
Divide each term by 3 and simplify.
x - 4 =
Cancel the common factor of 3 .
x - 4 = -1
Move all terms not containing x to the right side of the equation.
x = -1 + 4
Add -1 and 4.
<u>Hope this helps!</u>
x = 3
3(x - 4) = -3
Divide by 3
3/3(x - 4) = -3/3
x-4 = -1
Add 4 to each side
x-4+4 = -1+4
