Question

A fraction becomes 4/5, if 2 is added to both numerator and denominator, if however 4 is subtracted from both numerator and denominator, then the fraction becomes 1/2. The algebraic representation of situation is
) 5 − 4 + 2 = 0 , − = 0
) 5 − 4 + 2 = 0 , 2 − − 4 = 0
) + 4 = 0 , + 2 = 0
) ℎ

Answer 1

The algebraic representation of situation is 5x-4y+2=0 and 2x-y-4=0

Step-by-step explanation:

Lets take numerator as x

lets take denominator as y

so, When 2 is added the equation becomes

x+2/y+2 = 4/5

= 5x+10=4y+8

= 5x-4y+2=0 (i)

When 4 is subtracted from both

x-4/y-4 = 1/2

=2x-8=y-4

=2x-y-4=0 (ii)

So, equation (i) & equation (ii) are the algebraic equation
