Let m = Marian's age
Let s = sister's age
:
Write an equation for the statement:
"Marian's younger sister's age is 2 years greater than 1/2 Marian's age."
s = .5m + 2
:
"If Marian is 12 years old,"
m = 12
:
how old is her sister?
:
Replace m with 12 in the 1st equation
s = .5(12) + 2
s = 6 + 2
s = 8 yrs
