Question

X/2+y=0.8 and 7/y/2+x then the value x+y is

Answer 1

Answer:

x+y=-4.16+2.16/5

Step-by-step explanation:

(x/2+y=0.8)×2

x+2y=0.16..........i

7y+x+2=0

7y+x=-2............ii

solve i and ii

x+2y=0.16

x+7y=-2

-5y=2.16

y=2.16/5

put y=2.16/5 in equestion i

x+4.32=0.16

x=0.16-4.32

x=-4.16
