Question

let x/a+y/b=1 and x=2a find y ​

Answer 1

Answer:

Step-by-step explanation:

x/a+y/b=1

2a/a+y/b=1

2+y/b=1

2b+y/b=1

2b+y=1b

y=1b-2b

therefore,y=-b

Answer 2

Given:

x=2a

To Find:

Value of y=?

Solution:

x/a+y/b=1

2a/a+y/b=1

2+y/b=1

2b+y/b=1

2b+y=1×b

2b+y=b

y=b-2b

y= -1b

So the value of y is -1b.
