3(4x – 8) + 2 = 5 – 2(3 – 2x)

Answer 1

Resposta:

21/8

Explicação passo-a-passo:

$3(4x - 8) + 2 = 5 - 2(3 - 2x)\\12x - 24 + 2 = 5 -6 + 4x\\12x - 4x - 22 = -1\\8x = 21\\x = \frac{21}{8}$

Answer 2

3 ⋅ (4x – 8) + 2 = 5 – 2 ⋅ (3 – 2x)

    12x – 24 + 2 = 5 – 6 + 4x

       12x - 4x = 5 – 6 + 24 -2

                    8x = 21

                     x = 21

                           8
