Question 1021367
Call isha's age and majue's age NOW, x and y.  Then we can write
(1/2)x + 2y = 70  (let's multiply by two) and get
x + 4y = 140
In 5 years,
(x+5) + (y+5) = 75  or
x + y + 10 = 75  and
x + y = 65
Subtract this from the above and get
x + 4y = 140
-(x + y = 65)
---------------
3y = 75
y = 25
and then
x = 40
