x = age of the son
y = age of the father
x + y = 44
y = 2x
Substitute our second equation into our first equation.
x + 2x = 44. Combine the like terms.
3x = 44. Divide each side by 3
x = 44/3 or 14.7.
Substitute 44/3 into x for our second equation to find y
y = 2(44/3). Multiply 2 by 44/3
y = 88/3 or 29.3
