Your question is changed slightly. Assumption is that your second sentence stays for the past tense.

y, father
x, son

system%28x%2By=52%2Cy-3=2%2B3%2A%28x-3%29%29


Simplifying the past equation,
y-3=2%2B3x-9
y=3x%2B2-9%2B3
y=3x-4
-
x%2By=52
x%2B3x-4=52
4x=52%2B4
x=13%2B1
highlight%28x=14%29
-
x%2By=52
y=52-x
y=52-14
highlight%28y=38%29
