To solve this equation, we first need to distribute the 3/7 to both terms inside the parentheses:

(3/7) x - (3/7) 24 = x

Now we can simplify the equation:

(3x/7) - (72/7) = x

Next, we can combine the x terms on one side of the equation:

(3x/7) - x = 72/7

Now we can find a common denominator to combine the x terms:

(3x - 7x) / 7 = 72/7

Simplify the x terms:

-4x/7 = 72/7

Now we can solve for x by multiplying both sides by 7:

-4x = 72

Divide by -4 to solve for x:

x = -18

Therefore, the solution to the equation is x = -18.
