Which value of x makes the equation 9x − 10 = 143 true?

To find the value of \( x \) that makes the equation \( 9x - 10 = 143 \) true, follow these steps:

1. **Add 10 to both sides** of the equation to isolate the term with \( x \) on one side:
   \[
   9x - 10 + 10 = 143 + 10
   \]
   \[
   9x = 153
   \]

2. **Divide both sides** of the equation by 9 to solve for \( x \):
   \[
   \frac{9x}{9} = \frac{153}{9}
   \]
   \[
   x = 17
   \]

So, the value of \( x \) that makes the equation true is \( x = 17 \).
