Identify Fractions: Identify the expressions to be combined and note that they are fractions that need a common denominator.
Simplify Denominators: Recognize that the denominators (x−2y), (4y−2x), and (3x−6y) can be simplified and made common. Notice that (4y−2x) is −1(x−2y) multiplied by 2, and (3x−6y) is (x−2y) multiplied by 3.
Find LCD: Find the least common denominator (LCD) for the three fractions. The LCD for (x−2y), −2(x−2y), and 3(x−2y) is 6(x−2y).
Rewrite with LCD: Rewrite each fraction with the common denominator 6(x−2y). The first fraction is already x−2y1, so it needs to be multiplied by 66 to get the common denominator. The second fraction is −2(x−2y)1, so it needs to be multiplied by −3−3 to get the common denominator. The third fraction is 3(x−2y)1, so it needs to be multiplied by 22 to get the common denominator.
Multiply by 1: Multiply each fraction by the appropriate form of 1 to get the common denominator:(x−2y1)×(66)=6(x−2y)6(4y−2x1)×(−3−3)=6(x−2y)−3(3x−6y1)×(22)=6(x−2y)2
Combine Fractions: Combine the fractions now that they have a common denominator: 6(x−2y)6−(−6(x−2y)3)+6(x−2y)2
Add and Subtract Numerators: Add and subtract the numerators: 6−(−3)+2=6+3+2=11
Write Combined Fraction: Write the combined fraction with the common denominator: 6(x−2y)11
