To simplify the expression \(\frac{3}{4}(24x - 12)\), we can distribute \(\frac{3}{4}\) into the parentheses:
\[ \frac{3}{4} \times 24x - \frac{3}{4} \times 12 \]
Calculating each term:
- \(\frac{3}{4} \times 24x = 18x\)
- \(\frac{3}{4} \times 12 = 9\)
Now we can write the full expression after distribution:
\[ 18x - 9 \]
Thus, in the expression \(\frac{3}{4}(24x - 12) = \text{blank} + \text{blank}\), we can fill in:
\[ 18x + (-9) \]
So, the answer is:
- First blank: \(18x\)
- Second blank: \(-9\)
