Question

if 1 is added to both numerator and denominator of a fraction. Then it becomes 4/5. write the linear equations in two variables​

Answer 1

Answer:

let the fraction be x/y

1 is added means

x+1/y+1=4/5

5x+5=4y+4

5x-4y=-1

5 is subtracted means

x-5/y-5=1/2

2x-y=5

2 eqn multilply by 5 and 1 eqn by 2

2(5x-4y=-1)=10x-8y=-2

5(2x-y=5)=10x-5y=25

10x-5y=25

10x-8y=-2

x=7,y=9

then the fraction  is 7/9

Answer 2

Answer:

Step-by-step explanation:

let the fraction be x/y

1 is added means

x+1/y+1=4/5

5x+5=4y+4

5x-4y=-1

5 is subtracted means

x-5/y-5=1/2

2x-y=5

2 eqn multilply by 5 and 1 eqn by 2

2(5x-4y=-1)=10x-8y=-2

5(2x-y=5)=10x-5y=25

10x-5y=25

10x-8y=-2

x=7,y=9

then the fraction  is 7/9
