Answer:
and 
Step-by-step explanation:
First, we are told "sum of 5 times one number, x, and 4 times a second number, y, is 75":
(1)
Then, we are told "he sum of the two numbers is 18":
(2)
At this point we have our system of equations and now we are able to find the values of 
and 
.
So, let's begin by isolating from (2):
(3)
Substituting (3) in (1):
(4)
Finding :
(5) This is the value of
Substituting (5) in (1):

When given a slope, and y intercept, this means the question is asking us to write the equation in slope-intercept form, which is y = mx + b.
Plug in the values.
y = -2x + 4
Answer:
Step-by-step explanation:
5x-12=3x+20
plus 12 both sides
5x=3x+32
-3x both sides
2x=32
divide by 2 both sides
x=16
