Question

neha is 5 years younger to karishma. Twelve year ago, karishma was twice as old as neha convert it into algebraic equation.​

Answer 1

Answer:

Step-by-step explanation:

let present age of karishma is = x

and Present age of neha is = y

so....

x - y = 5....... equation (1 )

before 12 years ago age of karishma is = x- 12

before 12 years ago age of neha is = y -12

so as per 2nd statement. ...

x- 12 = 2 ( y -12 )...... .. equation (2 )

or, x-12 = 2y - 24

or, x - 2y = 12- 24
