Question

aftab tells his daughter ," seven years ago,i was seven times as old as you will be ,"(isn't this intersecting ?) represent this situation algebraically and graphically. on graph paper
​

Answer 1

ANSWER:.

Consider Aftab's age as x and his daughter's age as y.

Then , seven years ago,

Aftab's age =x−7

His daughter's age =y−7

According to the question,

x−7=7(y−7)

x−7=7y−49

x−7y=−49+7

x−7y=−42 …(i)

After three years,

Aftab's age =x+3

His daughter's age =y+3

According to the question,

x+3=3(y+3)

x+3=3y+9

x−3y=9−3

x−3y=6 …(ii)

On subtracting the two equations, we get

4y=48

or y=12

Substituting value of y in (2),

x−36=6

∴x=42
