Answer:
x = -6
Step-by-step explanation:
distribute 9(x+3) = 9x+27
9x+27 = 4x-3 subtract -27 and -4x on each side
9x-4x = -3-27 combine like terms
5x = -30 divide by 5
⇒ 9(x + 3) = 4x - 3
apply distributive method: a(b + c) = ab + ac
⇒ 9(x) + 9(3) = 4x - 3
multiply variables
⇒ 9x + 27 = 4x - 3
collect like terms
⇒ 9x - 4x = -3 - 27
subtract like terms
⇒ 5x = -30
divide both sides by 5
⇒ x = -6
