Answer

\( x = \frac{25}{8} \) or \( x = 3.125 \)

Solution

Solve the equation \( \frac{-3}{5}x+\frac{1}{6}=\frac{-1}{3}x-\frac{2}{3} \). Solve the equation by following steps: - step0: Solve for \(x\): \(\frac{-3}{5}x+\frac{1}{6}=\frac{-1}{3}x-\frac{2}{3}\) - step1: Rewrite the fraction: \(-\frac{3}{5}x+\frac{1}{6}=-\frac{1}{3}x-\frac{2}{3}\) - step2: Multiply both sides of the equation by LCM: \(\left(-\frac{3}{5}x+\frac{1}{6}\right)\times 30=\left(-\frac{1}{3}x-\frac{2}{3}\right)\times 30\) - step3: Calculate: \(-18x+5=\left(-\frac{1}{3}x-\frac{2}{3}\right)\times 30\) - step4: Calculate: \(-18x+5=-10x-20\) - step5: Move the expression to the left side: \(-18x+10x=-20-5\) - step6: Add and subtract: \(-8x=-20-5\) - step7: Add and subtract: \(-8x=-25\) - step8: Change the signs: \(8x=25\) - step9: Divide both sides: \(\frac{8x}{8}=\frac{25}{8}\) - step10: Divide the numbers: \(x=\frac{25}{8}\) The solution to the equation \(\frac{-3}{5}x+\frac{1}{6}=\frac{-1}{3}x-\frac{2}{3}\) is \(x=\frac{25}{8}\) or \(x=3.125\).

To solve the equation \[ \frac{-3}{5} x + \frac{1}{6} = \frac{-1}{3} x - \frac{2}{3}, \] let's first eliminate the fractions by finding a common denominator. The denominators are 5, 6, and 3. The least common multiple of these numbers is 30. Now we will multiply every term by 30 to get rid of the fractions: \[ 30 \left(\frac{-3}{5} x\right) + 30 \left(\frac{1}{6}\right) = 30 \left(\frac{-1}{3} x\right) + 30 \left(-\frac{2}{3}\right). \] This simplifies to: \[ -18x + 5 = -10x - 20. \] Next, we'll move all the \(x\) terms to one side and the constant terms to the other side. First, add \(10x\) to both sides: \[ -18x + 10x + 5 = -20. \] This simplifies to: \[ -8x + 5 = -20. \] Now, subtract 5 from both sides: \[ -8x = -25. \] Finally, divide by -8: \[ x = \frac{25}{8}. \] So, the solution to the equation is \[ x = \frac{25}{8}. \]
