# How do you solve for y given -3x-y+7=0?

Jun 3, 2017

$y = - 3 x + 7$

#### Explanation:

We can solve for $y$ in terms of $x$ using Algebra.

$- 3 x - y + 7 = 0$

Add $3 x$ to both sides of the equation.

$- y + 7 = 3 x$

Subtract $7$ from both sides of the equation.

$- y = 3 x - 7$

Multiply or Divide both equations by $- 1$

$y = - 3 x + 7$
