# How do you solve 3/4a + 5 = 20 ?

Apr 30, 2018

$a = 20$

#### Explanation:

Move all like terms to one side, then solve:

$\frac{3}{4} \left(a\right) = 20 - 5$

$\frac{3}{4} \left(a\right) = 15$

Can also be written as:

$\frac{3 a}{4} = 15$

$3 a = 15 \cdot 4$

$3 a = 60$

$a = \frac{60}{3}$

$a = 20$
