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.
