Question

2 years ago my age was x4 my son's. 8 years ago my age was x10 my son's. How old is my son now? Help! I need an equation to answer this, please.

Answer 1

x - your age
y - your son's age


`x-2=4(y-2)\\ x-8=10(y-8)\\\\ x-2=4y-8\\ x-8=10y-80\\\\ x=4y-6\\ x=10y-72\\\\ 4y-6=10y-72\\ 6y=66\\ y=11\\\\ x=4\cdot11-6\\ x=44-6\\ x=38`
