6x+5y=15 -7x-5y=-10These are the same x and y stuff
You can use elimination to solve this system. By adding the two equations together, you get: -x=5 Then solve for x by dividing both sides by -1: x=-5
Now that you have x, substitute that into one of the equations to solve for y. 6(-5)+5y=15 -30+5y=15 5y=45 And now divide both sides by 5 to solve for y: y=9
