Answer 3

To solve the equation 128 - 5 * (x - 9) = -17, follow these steps:

Step 1: Distribute the multiplication (apply the distributive property) 128 - 5x + 45 = -17

Step 2: Combine like terms (add or subtract terms with the same variable) 173 - 5x = -17

Step 3: Isolate the variable on one side of the equation. To do that, move the constant term to the other side by adding 17 to both sides: 173 - 5x + 17 = -17 + 17 190 - 5x = 0

Step 4: Now, isolate the variable term by moving the constant term to the other side. To do that, subtract 190 from both sides: 190 - 5x - 190 = 0 - 190 -5x = -190

Step 5: Finally, solve for x by dividing both sides by -5: x = -190 / -5 x = 38

So, the solution to the equation is x = 38.
