The sum of my dad's age and my grandfather's age is 163. The difference in their age is 21. Let x= my dad's age and let y= my grandfather's age. Write two equations representing the situation and solve this system using elimination OR substitution.
------
Equations:
d + g = 163
g - d = 21
------
Add and solve for "g"::
2g = 184
Grandpa's age = 92 yrs
Dad's age = 163-92
