X/6 + 2x/3 = 5 what is the value of x in the equation

ycow [4]

The value of x is 6 in the equation.

Step-by-step explanation:

Given equation is;

$\frac{x}{6}+\frac{2x}{3}=5$

Taking least common multiple

$\frac{x+4x}{6}=5$

Multiplying both sides by 6

$6*\frac{5x}{6}=5*6\\5x=30$

Dividing both sides by 5

$\frac{5x}{5}=\frac{30}{5}\\x=6$

The value of x is 6 in the equation.
