Answer:a = 1Step-by-step explanation:equation given:   a - 2(4 - a) = 7a - 12distribute and expand the equationa - 8 + 2a = 7a - 12combine similar terms:a + 2a - 7a = -12 + 8simplify:-4a = -4a = -4 / -4a = 1proof that a = 1 a - 2(4 - a) = 7a - 121 - 2(4 - 1) = 7(1) - 12 1 - 2(3) = 7 - 12 1 - 6 = -5 -5 = -5  therefore, the a = 1 is correct.

Steps to solve:a - 2(4 - a) = 7a - 12~Distribute left sidea - 8 - 2a = 7a - 12~Combine like terms on the left side-a - 8 = 7a - 12~Add 8 to both sides-a = 7a - 4~Subtract 7a to both sides-8a = -4~Divide -8 to both sidesa = 1/2Best of Luck!
