Let B = age of the boyfriend, and
G = age of the girlfriend.
Then, since their combined age is 36, that means that B + G = 36.
And since the boyfriend is 8 years older than the girlfriend, that means B = G + 8.
So now we have two equations, with two unknowns. The two unknowns are B and G. The two equations are ....
(1.) B + G = 36
(2.) B = G + 8
Let's take the value of B, from equation (2.), and substitute it for B in equation (1.):
(1) (G + 8) + G = 36
Remove the parentheses:
G + 8 + G = 36
Simplify:
2G + 8 = 36
Subtract 8 from both sides of the equation:
2G + 8 - 8 = 36 - 8
Simplify:
2G = 28
Divide both sides of the equation by 2:
2G/2 = 28/2
Simplify:
G = 14
So now we know the girlfriend is 14 years old.
And since their combined age is 36, so that 14 + B = 36,
then the boyfriend must be 36 - 14 = 22 years old.
So the answer is that the boyfriend is 22 years old and the girlfriend is 14.
The boyfriend is a cradle robber!

Lets say the age of girlfriend be x years.
Then age of the boyfriend would be (x+8) years.
it is given that, x + (x+8) = 36
2x+8=36
dividing by 2
x+4=18
x = 14.
So, the girlfriend's height is 14 and boyfriend age is (14+8 = 22).. .
it is kinda weird but you know maths.
