With a Fraction
Part of the Inequalities & Absolute Value section of Coddy's Algebra journey. Lesson 16 of 61.
To solve , add 1 to both sides, then multiply both sides by 2. Neither step changes the sign, because 2 is positive:
You can also clear the fraction first. Multiply every term by 2 to get , then add 2 to both sides. This gives the same answer in the same number of steps.
When a whole side is one fraction, clearing the denominator is a good first step. For , multiply both sides by 3 to get . Then subtract 1 from both sides to get .
