- Classifying linear solution sets Collect like terms on each side, then collect variable terms. A false constant equation means no solution; a true one means every real value is a solution.
- Clearing fractional coefficients Multiply every term on both sides by a nonzero common multiple of the denominators.
- Equations in mixed numeric representations Choose fractions or exact decimals. Keep each value unchanged when converting.
- Equations requiring collection of like terms Combine variable terms and constants separately on each side before solving.
- Equations with infinitely many solutions Collect like terms on each side, then collect variable terms. A false constant equation means no solution; a true one means every real value is a solution.
- Equations with no solution Collect like terms on each side, then collect variable terms. A false constant equation means no solution; a true one means every real value is a solution.
- Solving equations with expansion on both sides Expand both groups. Collect variable terms on one side, isolate the variable.
- Solving equations with one expansion Expand the parentheses first. Collect variable terms on one side, then isolate the variable. Check in the original equation.
- Solving equations with variables on both sides Collect variable terms on one side, then isolate the variable. Check in the original equation.
