Answer 1

Respuesta:

$\bold{ECUACIONES}$

$\boxed{\mathrm{4\left(x-2.5\right)=7\left(12.2-0.5x\right)}}$

Resolvemos

4(x - 2.5) = 4x - 10

7(12.2 - 0.5x) = 85.4 - 3.5x

4x - 10 = 85.4 - 3.5x

4x - 3.5x = 85.4 + 10

4x = -3.5x + 95.4

7.5x = 95.4

95.4/7.5 = 12.72

Solución:

$\boxed{\mathrm{x=12.72}}$
