Question

x+y=5 &9x=2y+7 tell me answer​

Answer 1

Step-by-step explanation:

9x=2y+7

9x-2y=7

because x+y=5 so x-y= -5

-5=7

7+5=12

Answer 2

Step-by-step explanation:

x+y=5and 9x=2y+7

so, x=5-y

put the vale of x in 9x=2y+7

9*5-y=2y+7

35-y-2y=7

35-3y=7

so, y=-28

and put the valu of y in x+y=5

x-28=5

x=5-28

x=-23
