hmm...

first let's distribute out the equations to get:

Alright, now let's solve for x (or y, it's your choice) for the first problem:

now take the second equation:

and also solve for x:

and now we can start solving stuff. First things first, you have to write down that:

So now we substitute:

so now multiply both sides by -11 and 5 to get:

now use the distributive property:

now move things around:

then divide:

Now you can solve for x.

On a side note,

is not a nice number, you should double check my work and see if my arithmetic is right.
