Answer:
x = 2/5 and y =1 (2/5, 1)
Step-by-step explanation:
I will assume that you meant y = -5x + 3. If that's the case, then we equate
y = -5x + 3 to y = 1, obtaining:
-5x = -2, so that x = 2/5 and y =1.
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
