# How do you solve x+3y=y+110 for y?

Sep 3, 2016

$y = \frac{110 - x}{2}$

#### Explanation:

Solve $x + 3 y = y + 110$ for $y$.

Subract $x$ from both sides of the equation.

$3 y = y + 110 - x$

Subtract $y$ from both sides.

$3 y - y = 110 + x$

Simplify $3 y - y$ to $2 y$.

$2 y = 110 + x$

Divide both sides by $2$.

$y = \frac{110 - x}{2}$
