Answer 1

Answer:

x = 23

y = 17

Step-by-step explanation:

$x + y = 40 \\ x - y = 6 \: \\ \\ 2x = 46 \\ x = 23 \\ \\ x + y = 40 \\ 23 + y = 40 \\ y = 40 - 23 \\ y = 17$

Hope it helps u

Answer 2

Step-by-step explanation:

here X+Y=40.......... 1

X-Y=6 .........2

so, now

let's add the equation 1 and 2,

we get X+Y+X-Y=40+26

2X=46

X=46/2

X=23

now let's put the value of X in equation 1,

23+Y=40

Y=40-23

Y=17

here is the answer

X=23

Y=17
