# How do you solve for y in x-2y=1 ?

Mar 13, 2016

color(green)(y =( x- 1)/2

#### Explanation:

$x - \textcolor{b l u e}{2 y} = 1$

Since we need to solve for $y$ we need to isolate the term containing $y$:

$x - 1 = \textcolor{b l u e}{2 y}$

$\textcolor{g r e e n}{2} y = x - 1$

$y = \frac{x - 1}{\textcolor{g r e e n}{2}}$

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