well just try it?
put x=1
and y=-5 and see what happens

Answer 10

your welcome.
Also remember when solving for anything and u end up with something like this,
a= 3.25 or b=3 or so on....
remember u can check if it correct by substituting the value back into the original equation to see if it makes sense.
