Question

answer correct and fast .​

Answer 1

Answer:

x=5

2x-y=11

2(5)-y=11

10-y=11

-y=11-10

-y=1

y=-1

Therefore y=-1 and x,y = (5,-1)

when y=-3

2x-(-3)=11

2x+3=11

2x=11-3

2x=8

x=8/2

x=4

Therefore x=4 and (x,y)=(4,-3)

when x=7

2(7)-y=11

14-y=11

-y=11-14

-y=-3

y=3

Therefore y=3 and (x,y)=(7,3)

when y=-5

2x-5=11

2x=11-5

2x=6

x=6/2

x=3

Therefore x=3 and (x,y)=(3,-5)
