Cheat Sheet
- Understand the Structure of Linear Equations -
Linear equations typically follow the form ax + b = c or ax = c, where a, b, and c are constants. Recognizing this layout helps you pinpoint which terms to move first when solving equations like 18x = 5/9 (Purplemath).
- Apply Inverse Operations in Order -
To isolate x, undo addition or subtraction before multiplication or division, ensuring you perform the same operation on both sides. For instance, if you have 18x + 5/9 = 7, subtract 5/9 from both sides first (Khan Academy).
- Handle Fractional Coefficients with Confidence -
When your equation has fractions, multiply both sides by the least common denominator (LCD) to clear them or use "keep-change-flip" to divide by a fraction. For 18x = 5/9, you'd multiply both sides by 9/5 to get x = (5/9)·(1/18)❻¹ (MathIsFun).
- Check Your Solution by Substitution -
After finding x, substitute it back into the original equation to verify both sides balance. This simple check catches sign slips or calculation errors before you finalize your answer (MIT OpenCourseWare).
- Avoid Common Pitfalls with Mnemonics -
Watch out for negative signs and fraction flips, which are frequent stumbling blocks. The mnemonic "Keep-Change-Flip" reminds you to keep the first fraction, change division to multiplication, and flip the second fraction (University of Cambridge).
