Question

X+y = 8 and x/y = 7,find y​

Answer 1

Answer:

X+y=8

X/y=7

X=7y

7y+y=8

8y=8

y=8/8

y=1

Answer 2

Step-by-step explanation:

x+y=8 (Given) - (1)

x/y=7 (Given) - (2)

From equation 1 and 2 we find that x = 8-y in first case and in second case x= 7y

Now both are the value of x so both will be equal to each other

8-y=7y

7y+y=8

8y=8

y= 8/8= y= 1

Therefore value of y = 1
