Question

X+y=15,x-y=3,then x and y are

Answer 1

Answer:

2x=15+3

X=18\2

X=9

X+y=15

9+y=15

y=15-9

y=6

Answer 2

Answer:

The value of x = 9 and the value of y = 6

Step-by-step explanation:

Given equations are

x+y = 15

x - y = 3

To find,

The value of x and y

Solution

We have the equations

x+y = 15 -------------------(1)

x - y = 3 --------------------(2)

Adding equations (1) and (2) we get

x+y +x-y = 15+3

2x = 18

x = 9

Substitute the value of 'x= 9' in equation (1) we get

9 + y = 15

y = 15 -9

y = 6

The value of x = 9 and the value of y = 6
