Answer 1

Im going to solve using elimination

2x+5y=-5
(-2) x+3y=3(-2) Mult. both sides by -2 so you can cancel out the x
______________
2x+5y=-5
-2x-6y=-6 The x's cancel out. Now Its time to solve for y
_______________
5y-6y= -y

-y= -11 y cannot be negative, so you will divide both sides by -1
-y/=-1= -11/-1 ----the why becomes positive and so does 11

y= 11 ----- now were going to substitute 11 for y in one of the original equations

Im using 2x+5y=-5

2x+5(11)= -5
2x+55= -5
-55 -55
_______________
2x= -60
2x/2 = -60/2 2's cancel out leaving x on one side

x= 30

your coordinates for this equation is

( 30, 11)
