the value of x will be the 63÷2 and the value of y will be the 23÷2

Answer 2

Answer:

x=63/2 and y=23/2

Step-by-step explanation:

let as take x,y as 2 numbers

if x+y=43,x-y=20 then

x=20+y

•20+y+y=43

•20+2y=43

•2y=43-20

•2y=23

•y=23/2

as we told x=20+y

x=20+23/2

=63/2

and then we got x and y.
