The correct Answer is:
To solve the equation \( 5 - 2\left(\frac{x}{3} + 1\right) = \frac{2}{3}x + 3 - 11x \), we will follow these steps: ### Step 1: Distribute the -2 on the left-hand side (LHS) \[ 5 - 2\left(\frac{x}{3}\right) - 2(1) = \frac{2}{3}x + 3 - 11x \] This simplifies to: \[ 5 - \frac{2x}{3} - 2 = \frac{2}{3}x + 3 - 11x \] ### Step 2: Combine like terms on the LHS \[ (5 - 2) - \frac{2x}{3} = \frac{2}{3}x + 3 - 11x \] This simplifies to: \[ 3 - \frac{2x}{3} = \frac{2}{3}x + 3 - 11x \] ### Step 3: Combine like terms on the right-hand side (RHS) \[ 3 - \frac{2x}{3} = \frac{2}{3}x + (3 - 11x) \] This simplifies to: \[ 3 - \frac{2x}{3} = \frac{2}{3}x - 11x + 3 \] Now, convert \( -11x \) to a fraction with a common denominator: \[ -11x = -\frac{33x}{3} \] So, we have: \[ 3 - \frac{2x}{3} = \frac{2x - 33x}{3} + 3 \] This simplifies to: \[ 3 - \frac{2x}{3} = \frac{-31x}{3} + 3 \] ### Step 4: Eliminate the constant term from both sides Subtract 3 from both sides: \[ -\frac{2x}{3} = \frac{-31x}{3} \] ### Step 5: Eliminate the fractions by multiplying through by 3 \[ -2x = -31x \] ### Step 6: Add \( 31x \) to both sides \[ -2x + 31x = 0 \] This simplifies to: \[ 29x = 0 \] ### Step 7: Divide both sides by 29 \[ x = 0 \] ### Step 8: Verify the solution Substituting \( x = 0 \) back into the original equation: LHS: \[ 5 - 2\left(\frac{0}{3} + 1\right) = 5 - 2(0 + 1) = 5 - 2 = 3 \] RHS: \[ \frac{2}{3}(0) + 3 - 11(0) = 0 + 3 - 0 = 3 \] Since LHS = RHS = 3, the solution is verified. ### Final Answer: \[ x = 0 \]
