-5(x – 3) = x + 27
multiply the bracket by -5
(-5)(x)=-5x
(-5)(-3)=15
-5x+15=x+27
Move +15 to the other side. Sign changes from +15 to -15.
-5x+15-15=x+27-15
-5x=x+27-15
-5x=x+12
Move +x to the other side. Sign changes from +x to -x.
-5x-x=x-x+12
-6x=12
Divide both sides by -6
-6x/-6=12/-6
Answer: x=-2
