Mother and daughter 2

The mother is 40 years older than her daughter. How old is the mother if her age is eight thirds age of daughter?

Correct answer:

m =  64

Step-by-step explanation:

$$\begin{gathered} m=40+d \\ m=8\mathrm{/}3\cdot d \\ m=64 \end{gathered}$$

m = 40 + d; m= 8/3d

m = 40 + d
m= 8/3•d

d-m = -40
8d-3m = 0

d = 24
m = 64
