Question

4 (5x-3)+64(3-x)-3(12x-4)=96

Answer 1

Vamos aos cálculos.

4 (5x-3)+64(3-x)-3(12x-4)=96

20x - 12 + 192 - 64x - 36x + 12 = 96

-80x = 96-192

x = -96/-80

x = 6/5

Answer 2

Resposta:

x= 1.2 ou 6/5

Explicação passo-a-passo:

$4(5x - 3) + 64(3 - x) - 3(12x - 4) = 96 \\ \\ 20x - 12 + 192 - 64x - 36x - + 12 = 96 \\ \\ 20x - 36x - 64x = 96 + 12 - 12 - 192 \\ \\ - 80x = - 96 \\ \\ ( - 1) \times - 80x = - 96 \times ( - 1) \\ \\ 80x = 96 \\ \\ x = \frac{96}{80} \\ \\ x = 1.2$
