Can anyone help me to learn how to solve systems of linear equations?
{-5x-5y=-5
{-40x-3y=2

$$a+b=c$$
$$2a+b=3c$$

Eliminate either a or b. Since b is easier to get rid of, multiply either the 1st or 2nd equation by a negative. Then simply add straight down as you would normally.

Where is your work? I'm not going to work your problem, just giving you an example. So figure it out from there.
