Answer:
x=4,y=2
Step-by-step explanation:
solve one of the equations for x/y and then plug it into the other
Answer:
the domain of the function is all real numbers less than or equal to 0
Let x be one number and y be the other.
#1 - Set up a system of equations.
4x = y
x + y = 45
#2 - Solve the system by substitution.
x + (4x) = 45
5x = 45
x = 9
(9) + y = 45
y = 36
