3x+y=8
y=8-3x
5x+3(8-3x)=8
5x+24-9x=8
-4x+24=8
-4x=-16
x=4
5x+3y=8
5(4)+3y=8
20+3y=8
3y=-12
Y=-4
5x+3y=8
5(4)+3(-4)=8
20+-12=8
8=8
Answer: A
Step-by-step explanation:
The ratio is simply 2:5
You are comparing the two times
5x(8 - 4)/4 - 2
Remember to follow PEMDAS.
First, subtract 8 and 4
8 - 4 = 4
5x(4)/4 - 2
Next, follow the left -> right rule, and multiply 5x and 4
5x(4) = 20x
Divide by 4
20x/4 = 5x
Finally, note that one has a variable, and the other has a constant, and so you cannot combine.
5x - 2 is your answer

Answer:
Step-by-step explanation:
(47+1)/(3-6) = 48/-3 = -16
y + 1 = -16(x - 6)
y + 1 = -16x + 96
y = -16x + 95
