The correct Answer is:
To solve the equation \(\frac{3x}{5} = \frac{x + 2}{3}\), we will follow these steps: ### Step 1: Cross Multiply We start by cross multiplying to eliminate the fractions: \[ 3 \cdot (x + 2) = 5 \cdot 3x \] This simplifies to: \[ 3(x + 2) = 5(3x) \] ### Step 2: Distribute Next, we distribute on both sides: \[ 3x + 6 = 15x \] ### Step 3: Rearrange the Equation Now, we will rearrange the equation to isolate \(x\). We can subtract \(3x\) from both sides: \[ 6 = 15x - 3x \] This simplifies to: \[ 6 = 12x \] ### Step 4: Solve for \(x\) Now we can solve for \(x\) by dividing both sides by 12: \[ x = \frac{6}{12} \] This simplifies to: \[ x = \frac{1}{2} \] ### Final Answer Thus, the value of \(x\) is \(\frac{1}{2}\). ---
