# How do you solve the system of equations #-8x + 4y = - 12# and #- x - y = - 3#?

##### 1 Answer

#### Explanation:

Equation 1:

Equation 2:

Because its easier to work with positive values, I'm going to multiple both sides of equation 2 by -1.

I'm going to make

Substitute this value for

Solve for

Then combine the like terms

Subtract 12 from both sides of the equation.

Multiply both sides of the equation by -1 to make them positive.

Divide both sides of the equation by 12 to leave

Now we've found
