Answer: y = 48/x
Step-by-step explanation:
y ∝ 1/x
Introducing the proportionality constant, we have
y = k/x
substituting the value of x and y , we have
6 = k/8
k = 48
Therefore the equation becomes
y = 48/x
Answer:
see below
Step-by-step explanation:
-7(x+2)+4x=6(2x-4)
Distribute
-7x -14 +4x = 12x -24
Combine like terms
-3x-14 = 12x-24
Add 3x to each side
-3x-14+3x = 12x-24+3x
-14 = 15x-24
Add 24 to each side
-14+24 = 15x -24+24
10 = 15x
Divide each side by 15
10/15 =15x/15
2/3 =x
