Question

Alguien me podría ayudar con esto x favor se los agradezco 3(x-4)=5x-36

Answer 1

$3(x - 4) = 5x - 36 \\ = 3x - 3 \times 4 = 5x - 36 \\ = 3 x - 12 = 5x - 36 \\ = 3x - 5x = - 36 + 12 \\ = 3 - 5x = - 36 - 12 \\ = - 2x = - 24 \\ = 2x \div ( - 2) = - 24 \div ( - 2) \\ = x = 24 \div 2 \\ = x = 12$
