# How do you solve the following system: x+3y=-2, 6x + 7y = -9 ?

Mar 5, 2018

$x + 3 y = - 2$
$6 x + 7 y = - 9$

multiply first equation by 6 -> $6 x + 18 y = - 12$

subtract the two equations to end up with: $11 y = - 21$

#### Explanation:

After subtracting the two equations:

Solve for y then substitute it into one of either equations and find the value of x.
