Question 339802
let henry's age = x
Daisy's age be y
{{{(x/2) +(y/3)= 11}}
{{{(3x+2y)/6 =11}}}
3x+2y=6*11
3x+2y=66.....................1
...
6 years from now
x+6+y+6 = 40 years
x+y+12=40
x+y=40-12
x+y= 28 .......................2
multiply equation 2 by -2 and add the equations
-2x-2y=-56
3x+2y=66
x=10 Henry's age
plug value of x in eauation 2
x+y =28
10+y=28
y=28-10
y=18 Daisy's age
