Solve the equation by following steps:
- step0: Solve for \(x\):
\(\frac{3}{4}x+\frac{2}{3}=\frac{3}{8}+\frac{5}{6}\)
- step1: Add the numbers:
\(\frac{3}{4}x+\frac{2}{3}=\frac{29}{24}\)
- step2: Move the constant to the right side:
\(\frac{3}{4}x=\frac{29}{24}-\frac{2}{3}\)
- step3: Subtract the numbers:
\(\frac{3}{4}x=\frac{13}{24}\)
- step4: Multiply by the reciprocal:
\(\frac{3}{4}x\times \frac{4}{3}=\frac{13}{24}\times \frac{4}{3}\)
- step5: Multiply:
\(x=\frac{13}{18}\)
Solve the equation \( \frac{1}{5} x+\frac{2}{3}=\frac{3}{8}+\frac{3}{5} \).
Solve the equation by following steps:
- step0: Solve for \(x\):
\(\frac{1}{5}x+\frac{2}{3}=\frac{3}{8}+\frac{3}{5}\)
- step1: Add the numbers:
\(\frac{1}{5}x+\frac{2}{3}=\frac{39}{40}\)
- step2: Move the constant to the right side:
\(\frac{1}{5}x=\frac{39}{40}-\frac{2}{3}\)
- step3: Subtract the numbers:
\(\frac{1}{5}x=\frac{37}{120}\)
- step4: Multiply by the reciprocal:
\(\frac{1}{5}x\times 5=\frac{37}{120}\times 5\)
- step5: Multiply:
\(x=\frac{37}{24}\)
Solve the equation \( \frac{3}{4} x-\frac{7}{9}=\frac{2}{7} \cdot\left(\frac{3}{2} x+\frac{14}{3}\right) \).
Solve the equation by following steps:
- step0: Solve for \(x\):
\(\frac{3}{4}x-\frac{7}{9}=\frac{2}{7}\left(\frac{3}{2}x+\frac{14}{3}\right)\)
- step1: Multiply the terms:
\(\frac{3}{4}x-\frac{7}{9}=\frac{3}{7}x+\frac{4}{3}\)
- step2: Multiply both sides of the equation by LCM:
\(\left(\frac{3}{4}x-\frac{7}{9}\right)\times 252=\left(\frac{3}{7}x+\frac{4}{3}\right)\times 252\)
- step3: Calculate:
\(189x-196=\left(\frac{3}{7}x+\frac{4}{3}\right)\times 252\)
- step4: Calculate:
\(189x-196=108x+336\)
- step5: Move the expression to the left side:
\(189x-108x=336+196\)

\(81x=336+196\)
- step7: Add and subtract:
\(81x=532\)
- step8: Divide both sides:
\(\frac{81x}{81}=\frac{532}{81}\)
- step9: Divide the numbers:
\(x=\frac{532}{81}\)
Solve the equation \( \frac{2}{3}(x-1)+2=\frac{2}{3}+\frac{12}{10} \cdot \frac{5}{3} \).
Solve the equation by following steps:
- step0: Solve for \(x\):
\(\frac{2}{3}\left(x-1\right)+2=\frac{2}{3}+\frac{12}{10}\times \frac{5}{3}\)
- step1: Simplify:
\(\frac{2}{3}x+\frac{4}{3}=\frac{8}{3}\)

Solve the equation by following steps:
- step0: Solve for \(x\):
\(\frac{5}{10}x+7=\frac{4}{3}-\left(x-\frac{7}{3}\right)\)
- step1: Reduce the fraction:
\(\frac{1}{2}x+7=\frac{11}{3}-x\)
- step2: Multiply both sides of the equation by LCM:
\(\left(\frac{1}{2}x+7\right)\times 6=\left(\frac{11}{3}-x\right)\times 6\)
- step3: Calculate:
\(3x+42=\left(\frac{11}{3}-x\right)\times 6\)
- step4: Calculate:
\(3x+42=22-6x\)
- step5: Move the expression to the left side:
\(3x+6x=22-42\)
- step6: Add and subtract:

- step7: Add and subtract:
\(9x=-20\)
- step8: Divide both sides:
\(\frac{9x}{9}=\frac{-20}{9}\)
- step9: Divide the numbers:
\(x=-\frac{20}{9}\)
