3
Solving Equations with Fractions
Isolate the “y” by subtracting 2/7 from each side. Isolate the “x” by adding 2/5 to both sides. We found a common denominator and renamed our fractions so we could add them.
4
To isolate the variable you need to divide both sides by 2/3. When you divide fractions you multiply by the reciprocal so we multiply both sides of the equation by 3/2. To isolate the variable you have to subtract 8 and multiply by 5/2.
6
Closure How is solving equations with decimals and fractions different than equations with integers? How are they alike?
