Try to do it mentally by locating the sums of 36 and then decreasing the second digit and increasing first digit accordingly start from 18+18

Answer 2

Answer:

X=23

Y=13

Step-by-step explanation:

Let the numbers be X and Y

X+Y=36

X=36-y

X-Y=10

(36-Y)-Y=10(put value of X)

36-2Y=10

-2Y=10-36

Y= -26/-2

Y=13

X=36-Y

X=36-13

X= 23
