Problema Solution
Grandma is seven times as old as her grandson is now. If their ages add up to 96, how old is Grandma? Let the grandson’s age be x years
Answer provided by our tutors
Let the grandson`s age be x years
G: Grandma
G=7x
G+x=96
Either substitute and solve for the grandson's age and then find the grandma's age from there, or change the first equation slightly and substitute to find the grandmother's age directly
