Answer: y = x + 4
Step-by-step explanation:
Since the total number of gasoline is given to be "y", with an initial quantity of filled gasoline to be "4" and the quantity of unfilled gasoline to be "x".
Therefore, the summation of the filled and unfilled quantity of gasoline will be "x + 4" which is equal to the total capacity of the tank "y".

The answer for the given equation is x = 3.5.
<u>Step-by-step explanation</u>:
Given, 2 / 3 (3x + 6) = 4x + 3
Step 1:
Rearranging the given equation by subtracting the right side of the equation to the left side.
                            2 / 3 (3x + 6) - 4x + 3 = 0
Step 2:
Taking out the like terms, the equation becomes
                           (2 / 3)  3 (x + 2) - (4x - 3) = 0
 3 (x + 2) - (4x - 3) = 0
                           ⇒   2 (x + 2) - (4x - 3) = 0
Step 3:
Solving the equation for the value of x,
                           ⇒    2x + 4 - 4x + 3 = 0
                           ⇒    -2x + 7 = 0
                           ⇒     -2x = -7
                           ⇒     x = 7 / 2 = 3.5.
Hence the value of x = 3.5.
