Question

How do you solve $\frac{x}{2}+\frac{x}{4}=5?$

Answer 1

$x=\frac{20}{3}$
Explanation:
Make the two fractions have the same denominator
$\frac{x}{2}+\frac{x}{4}=\frac{2x}{4}+\frac{x}{4}$
Simplify the equation
$\frac{2x}{4}+\frac{x}{4}=\frac{3x}{4}$
Now we have $\frac{3x}{4}=5$
Multiply both sides of the equations by $4$
$3x=20$
Divide both side by $3$ to isolate the variable
$x=\frac{20}{3}$
