Let's simplify the equation step by step:

5 - 7x + 4 = 10x - 3 - 2x + 7 - 15x + 5

Combine like terms on both sides of the equation:
(-7x - 2x - 15x) + (5 + 4) = (10x - 3 + 7 + 5)

-24x + 9 = 10x + 9

Move variables to one side and constants to the other side:
-24x - 10x = 9 - 9

-34x = 0

Divide both sides by -34 to solve for x:
x = 0

Therefore, the solution to the equation is x = 0.
