in for
in the first equation. You will get
.
4.) Distribute. Your equation now looks like this:
.
5.) Combine like terms. You will get
.
6.) Subtract 6 from both sides. You get
. We can learn that Y=0.
7.) Go back to either equation and put 0 in for y.
8.) In the top equation, it would look like
and the bottom equation would look like
. We basically got our answer of
, but we will plug it into the
equation, and in-fact, we get x = -3.
Answer:
