Answer:

x = 5

Step-by-step explanation:

Isolate x:

3x + 2 = 6x - 13

Subtract 3x from both sides:

2 = 3x - 13

Add 13 to both sides:

15 = 3x

Divide each side by 3:

5 = x

The equation y =
-Dominant- [34]

Answer:

The  constant of proportionality k = 12

Hence, option A is true.

Step-by-step explanation:

We know that when 'y' varies directly with 'x', we get

y ∝ x

y = kx

Where 'k' is called the constant of proportionality.

In our case,

The given equation is

y = 12x

comparing with the equation y = kx, we can say

k = 12 which is the constant of proportionality.

Therefore, we conclude that:

The  constant of proportionality k = 12

Hence, option A is true.
