Answer:
40 years
Step-by-step explanation:
Hulian and Thomas together is 65 years
let us suppose hulian is X
now, so Thomas is x+15
so x+x+15=65
so 2x = 65-15
2x=50
x=25
Hulian is 25
and Thomas is 25+15=40
2x2-6x= - 8
Simplify both sides
2x(2) = 4x
Combine like terms
4x + (-6x) =-8
-2x = -8
Divide each side by -2
X = 4
