Step-by-step explanation:

X+Y=35

X-Y=15

ADD

2X=50

X=25

Y=10

Answer 2

Answer:

x=25 , y=10

Step-by-step explanation:

     x + y = 35(equation 1)

     x - y = 15 (equatio 2)

or,  x = 15 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 35

15 + y + y = 35

15 + 2y = 35

2y = 20

y = 10

Putting the value of y in equation 1,we get

   x+y=35

or,x+10=35

or,x=35-10

orx=25
