Let's solve for x in the equation:

x + (x - 75) + (x - 75) * 3 = 825

First, distribute the 3 to the terms inside the parentheses:

x + x - 75 + 3x - 225 = 825

Combine like terms:

5x - 300 = 825

Add 300 to both sides of the equation:

5x = 1125

Divide by 5:

x = 225

Therefore, the value of x is 225.
