8х-15,3=6х-3,3

To solve the equation \( 8x - 15.3 = 6x - 3.3 \), follow these steps: 1. **Isolate the variable \( x \)**: - Subtract \( 6x \) from both sides: \[ 8x - 6x - 15.3 = -3.3 \] This simplifies to: \[ 2x - 15.3 = -3.3 \] 2. **Get rid of the constant on the left-hand side**: - Add \( 15.3 \) to both sides: \[ 2x = -3.3 + 15.3 \] Calculating the right side: \[ 2x = 12 \] 3. **Solve for \( x \)**: - Divide both sides by 2: \[ x = \frac{12}{2} = 6 \] Thus, the solution is \( x = 6 \).
