To solve this equation for X, we can follow these steps:

First, we simplify the expression inside the parentheses:
13 - X/2 = 13 - 0.5X

Next, we substitute this simplified expression back into the equation and solve for X:
19 + 7 * (13 - 0.5X) = 75
19 + 91 - 3.5X = 75
110 - 3.5X = 75

Subtract 110 from both sides:
-3.5X = -35

Divide by -3.5 on both sides to solve for X, thus:
X = 10

Therefore, X = 10 would make the equation true.
