Question

Pls answer my question fast............

Answer 1

Daughter age = x
Mother age = 2x+8
Sum of ages = 56
= x + (2x+8) =56
= 3x + 8 =56
=3x = 48
x = 16
Hence, daughters age = 16
Mom age = 40

Answer 2

Let Mother's age be x and Daughter's age be y.
Given:
x=2y+8
=>x-2y=8.......(I)
x+y=56........(II)
Change the signs of eq(II)
-x-y=-56-(x-2y=8)
-3y=-48
y=16.......
x+y=56
x=56-y
x=56-16
x=40.......
