# How do you solve (x+3)/4=7/8?

May 20, 2018

Multiplying both sides by $8$ then we get: $2 \left(x + 3\right) = 7$ expanding $2 x + 6 = 7$ so $2 x = 1$ and we get $x = \frac{1}{2}$

#### Explanation:

$8 \frac{x + 3}{4} = 2 \left(x + 3\right) = 2 x + 6$

$x = \frac{1}{2}$

#### Explanation:

Cross multiply as shown described below:

$\frac{x + 3}{4} = \frac{7}{8}$

$\left(x + 3\right) \times 8 = 7 \times 4$

$8 x + 24 = 28$

$8 x = 28 - 24$

$8 x = 4$

$x = \frac{4}{8}$

$x = \frac{1}{2}$

$\frac{1}{2}$

#### Explanation:

$\frac{x + 3}{4} = \frac{7}{8}$

cross multiply:

$8 \left(x + 3\right) = 4 \cdot 7$

$8 x + 24 = 28$

$8 x = 4$

$x = \frac{4}{8} = \frac{1}{2}$
