-7x + 2y = 36 and 2x - 3y = -3

-7x + 2y = 36 and 2x - 3y = -3

8x+14y=4 -6x-7=-10

Elimination Form: 2x/3 - 4y/5 = 1 and 3x-y=-7

Elimination Form: 2x/3 - 4y/5 = 1 and 3x-y=-7

Elimination Form: 2x/3 - 4y/5 = 1 and 3x-y=-7

-2x + 4y + 4z = 7 -2x + 3y - z = 1 -4x + 2y - 4z = -4

−2x+5y=13 16x+3y=25
