Answer 1

Respuesta:

x=3

Explicación paso a paso:

$\frac{x+4}{3}-\frac{x-4}{5}=2+\frac{3x-1}{15}$

---------------------------------------------------------

• MCM de  3, 5 y 15:

03-05- 15 l 3

01-05-05 l 5

01- 01- 01 l

MCM = 3x5 = 15

---------------------------------------------------------

$\frac{x+4}{3}\cdot \:15-\frac{x-4}{5}\cdot \:15=2\cdot \:15+\frac{3x-1}{15}\cdot \:15$

$5\left(x+4\right)-3\left(x-4\right)=30+3x-1\\5\left(x+4\right)-3\left(x-4\right)=3x+29$

---------------------------------------------------------

• $5\left(x+4\right)-3\left(x-4\right)$

$=5x+20-3\left(x-4\right)\\=5x+20-3x+12\\=2x+32$

---------------------------------------------------------

$2x+32=3x+29\\2x-3x=29-32\\-x=-3\\x=3$
