Answer:
x = 5 and y = 3
Step-by-step explanation
y crosses out so you are left with
4x = 20 (divide by 4)
x = 5
plug x into either equation
5 + y = 8 (subtract 5)
y = 3
We want to see if the given function represents a linear function.
We will see that yes, it does.
So we have the function:
y = f(x) = 30 + 5*x
And a general linear function is written as:
y = a*x + b
where a is the slope and b is the y-intercept.
Comparing these two, we can see that both have the same general shape, thus, our function is also a linear function.
A graph of our function also can be seen below, where it is evident that it is a line.
