Question

What is the solution for these three equations?
1/2 x - 2y = 4 and 4y - x = -8

3x + 2y = 6 and y = -3/2 x - 1

3x - 2y = 6 and 5x + 3y = -9

Answer 1

1/2 x - 2y = 4 and 4y - x = -8 x=8,y=0

3x + 2y = 6 and y = -3/2 x - 1 I couldn't solve this.


3x - 2y = 6 and 5x + 3y = -9 x=0,y=-3

Answer 2

thank you! and I already solve it no problem :)
