Time gone

Square of Richard age equals the age of his mother. When he will bw two times older then his mom will be 7/2 times older than he. How old is Richard and his mom?

Result

r =  6
m =  36

Solution:

r2=m m+r=7/2 2r m=6r r2=6r r=6r^2=m \ \\ m+r=7/2 \cdot \ 2r \ \\ m=6r \ \\ r^2=6r \ \\ r=6
m=6r=6 6=36m=6r=6 \cdot \ 6=36
