Question

resuelve:
$\frac{3x - 7}{3} + \frac{2x + 5}{4} = \frac{14 - x}{5}$
​

Answer 1

Respuesta:

la respuesta es $x=\frac{233}{102}$

Explicación:

$20\left(3x-7\right)+15\left(2x+5\right)=12\left(-x+14\right)$

$20\left(3x-7\right)+15\left(2x+5\right)=12\left(-x+14\right)$

$20\left(3x-7\right)+15\left(2x+5\right)$

$12\left(-x+14\right)$

$90x-65=-12x+168$

$90x-65+65=-12x+168+65$

$90x=-12x+233$

$90x+12x=-12x+233+12x$

$102x=233$

$\frac{102x}{102}=\frac{233}{102}$

$x=\frac{233}{102}$
