Question

2x / 3 - 4( x /5 - 1/6 )= 1 / 15​

Answer 1

Respuesta:

1

 

Simplifica  2\times \frac{x}{3}2×3x  a  \frac{2x}{3}32x.

\frac{2x}{3}-4(\frac{x}{5}-\frac{1}{6})=\frac{1}{15}32x−4(5x−61)=151

2

 

Multiplica ambos lados por 33.

2x-12(\frac{x}{5}-\frac{1}{6})=\frac{1}{5}2x−12(5x−61)=51

3

 

Expandir.

2x-\frac{12x}{5}+2=\frac{1}{5}2x−512x+2=51

4

 

Simplifica  2x-\frac{12x}{5}+22x−512x+2  a  -\frac{2x}{5}+2−52x+2.

-\frac{2x}{5}+2=\frac{1}{5}−52x+2=51

5

 

Resta 22 en ambos lados.

-\frac{2x}{5}=\frac{1}{5}-2−52x=51−2

6

 

Simplifica  \frac{1}{5}-2
