Question

if x + y = 65 and x – y = 35 then find the value of x and y ​

Answer 1

Answer:

hey mate

X=50

y= 15

Step-by-step explanation:

X+y=65

y=65-x

substituting the values

x-y=35

x-(65-x)=35

x-65+X=35

2x-65=35

2x=35+65

2x=100

X=100/2

x= 50

putting the value of X

50+y=65

y=65-50

y=15

Answer 2

Answer:

In,

x + y = 65

y = 65 - x .... (eq.1)

In,

x - y = 35

Putting value of y in the equation

x - ( 65 - x) = 35

x - 65 + x = 35

2x = 35 + 65

2x = 100

x = 100/2

x = 50

now putting value of x in (eq.1)

y = 65 - x

y = 65 - 50

y = 15

Therefore, x = 50

y = 15
