Question

KnowledgeBoat · Accepted Answer

We have: 7 - 2(5 - 3x) = 4(x - 3) + 5 ⇒ 7 - 10 + 6x = 4x - 12 + 5 [Removing brackets] ⇒ -3 + 6x = 4x - 7 ⇒ 6x - 4x = -7 + 3 [Transposing -3 to RHS and +4x to LHS] ⇒ 2x = -4 ⇒ x = ⇒ x = ∴ x = -2 Check: LHS = 7 - 2(5 - 3x) = 7 - 2[5 - 3(-2)] = 7 - 2(11) = -15 RHS = 4(x - 3) + 5 = 4(-2 - 3) + 5 = -20 + 5 = -15 Hence, LHS = RHS.
