Question

resolver 4-9x/5 - 2(3-4x)/2-1=x

Answer 1

Respuesta:

$4-9\cdot \frac{x}{5}-\frac{2\left(3-4x\right)}{2}-1=x$

$4-\frac{9x}{5}-\frac{2\left(-4x+3\right)}{2}-1=x$

$4-\frac{9x}{5}-\left(3-4x\right)-1=x$

$-\frac{9x}{5}-\left(3-4x\right)=x-3$

$-9x-\left(3-4x\right)\cdot \:5=5x-15$

$11x-15=x\cdot \:5-15$

$11x=5x$

$6x=0$

$x=0$
