1. Problem Description

The problem asks us to solve the equation 3(x9)=42(x+2)3(x - 9) = 4 - 2(x + 2) for xx.

2. Solution Steps

We start by expanding both sides of the equation:
3(x9)=42(x+2)3(x - 9) = 4 - 2(x + 2)
3x27=42x43x - 27 = 4 - 2x - 4
3x27=2x3x - 27 = -2x
Now, we add 2x2x to both sides:
3x27+2x=2x+2x3x - 27 + 2x = -2x + 2x
5x27=05x - 27 = 0
Next, we add 27 to both sides:
5x27+27=0+275x - 27 + 27 = 0 + 27
5x=275x = 27
Finally, we divide both sides by 5:
5x5=275\frac{5x}{5} = \frac{27}{5}
x=275x = \frac{27}{5}

3. Final Answer

x=275x = \frac{27}{5}
The answer is (C).
