I'm solving your system by substitution.
2x-4=5, 5x+4y =2
Step# 1: solve for x
2x - 4+ 4= 5 + 4( add +4 to both sides)
2x = 9
x = 9/2
Step# 2: solve for y
5(9/2) + 4y = 2
4y + 45/2 = 2
4y 45
y = 45/4 = 11.25
The answer is 5
All of them are 100
5 are hot

Step-by-step explanation:
there really is no step by step explanation :)
If f(1) =5-2(1)
F(2)=5-2(2)
