Please help me with this system of equations problem
LekaFEV [45]

Answer:

5x-2y=3

-3x+4y=1

5x-2y=-3x+4y+2

+2y

5x=-3x+6y+2

+3x

8x=6y+2

divide by 2

4x=3y+1

-3y+4x=1

wait so that means that -3x+4y=-3y+4x so that means that both x and y are equal so lets just say their the same

-3x+4x=1

x=1

y=1

Hope This Helps!!!
