Answer:

32 years old

Step-by-step explanation:

Let Ale's age be x years old today.

Theo's age= x+10

In 4 years ,

Ale's age= x+4

Theo's age= x+10+4= x+14

Sum of their age= 82

x+4 + x+14= 82

2x +18= 82 (Simplify)

2x= 82 -18 (bring constant to 1 side)

2x= 64 (simplify)

x= 64 ÷2

x= 32

Thus, Ale is 32 years old today.
