Question

Find the Solution to the following system of equations
-2x+5y=8
2x+2y=6

Answer 1

-2*x+5*y=8 simplifies to -2*x+5*y-8=0

so hard huh?

Answer 2

you can take and combine like terms so the -2x and +2x will cancel. then just add up your y's so you will have
7y =14
y= 7
then just plug back in
2x+2(7)=6
2x=-8
x=-4

to check yourself, go
2(-4)+2y=6
-8+2y=6
2y=14
y=7

Answer 3
