Answer:
Step-by-step explanation:
tyler is x years old
t = x
samantha is 4 years older then tyler...
x + 4....this is samanthas age
three times samanthas age = 60
3(x + 4) = 60
3(x + 4) = 60 <=== this is an equation for tylers age....x = tylers age
3x + 12 = 60
3x = 60 - 12
3x = 48
x = 48/3
x = 16 <==== tyler is 16 years old
samantha is : x + 4.....16 + 4 = 20 <=== samantha is 20
