Answer 2

Step-by-step explanation:

the answer will be

A) 3x-2y=8

2x+3y=1

5x+5y=9

x-y=7...... multiply in this equation by 5

5x-5y=35

5x+5y=9

5x-5y=35

10x=44

x=22/5

5(22/5)+5y=9

22+5y=9

5y=-13

y=-13/5

B) 3x-y,=-8

3x-y=24

x=16

3(16)-y=24

48-y=24

48-y-24=0

-y-24=0

y=-24

c) lx-y=m

x+my=1

d) 10x-2y=20

10x-2y=20

x=0

y=-10
