We are told that y varies directly with x.
Therefore
y = k*x
where
k = the constant of variation
The given table and the ratio of k=y/x is shown below.
x y k
--- ------ --------
6 10 1.667
9 15 1.667
12 20 1.667
15 25 1.667
Answer:
k = 1.667
y = 1.667x
2 = X = -1

2. 2(4x+2) - (x-4) = 3(x+2)
Expand tge expression
= 8x + 4 -x +4 = 3x + 6
CLT ( Combine like terms)
= 7x + 8 = 3x + 6
Rearrange the terms
7x - 3x = 6 - 8
CLT
4x = -2
Divide both sides by 4
x = -2
4
x = -1
