Question

System Of Equations Elimination Method
1. -3x+10y=11, -8x+2y=-20
2. 4x+16y=-19, -8x+2y=10
3. 2x+6y=-2, -x+2y=6
4. -8x-y=-13, 5x-3y=-10
5. -4x+6y=4, -x+8y=1
6. -x+y=-5, 7x-3y=23
7. -9x-5y=26, 4x-4y=-24

Answer 1

1. x = 3, y = 2
2. x = -99/68, y = -14/17
3. x = -4, y = 1
4. x = 1, y = 5
5. x = -1, y = 0
6. x = 2, y = -3
7. x = 14, y = 20

I attached the pictures with the work.
