Hi guys, I really need help. Okay so here it is. use elimination to solve each system of equations x+y=2 -3x+4y=15

OpenStudy (nottim):

Rearrange one of the equations to solve for x or y. Then, substitute it into the other equation.

OpenStudy (anonymous):

Could you explain to me how to do that

OpenStudy (nottim):
