To solve the equation, we can start by simplifying the expression on the left side:

150 - 50(x - 12) = 50

Distribute the -50 to both terms inside the parentheses:

150 - 50x + 600 = 50

Combine like terms:

-50x + 750 = 50

Next, subtract 750 from both sides of the equation:

-50x = -700

Finally, divide both sides by -50 to solve for x:

x = -700 / -50

x = 14

Therefore, the solution to the equation is x = 14.
