Question

calcular el valor de x en la ecuacion 3(x-2) + 2(x-3) =7(a-4)

Answer 1

resolución

3x - 6 + 2x - 6 = 7x - 4

5x + 12 = 7x - 4

2x = 16

x = 8

Answer 2

Solucion.

Calculamos la ecuación.

$3(x-2)+2(x-3)=7(a-4)\\\\3x-6+2x-6=7a-28\\\\5x-6-6=7a-28\\\\5x-12=7a-28\\\\5x=7a-28+12\\\\5x=7a-16\\\\x=\frac{7a-16}{5}$
