Respuesta :
Nick = n
Ray = r
n=3r-30
n+r=74
3r-30+r=74
4r-30=74
4r=104
r=26
n=26*3-30
n=78-30
n=48
Nick is 48 years old and Ray is 26 years old
Hope this helps.

The age of Nick will be 48 years and the age of Ray will be 26 years.
What is the linear system?
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Let N be the age of Nick and R be the age of Rays.
Nick is 30 years, less than 3 times Ray's age.
N = 3R – 30 …1
If the sum of their ages is 74.
N + R = 74
N = 74 – R …2
From equation 1 and 2, we have
3R – 30 = 74 – R
4R = 104
R = 26 years
Then the age of Nick will be
N = 74 – 26
N = 48 years
