-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
