Question

Show all work to solve 2 over x plus 1 over 9 equals 1 over 3. Use complete sentences to explain how to solve this equation.

Answer 1

(2/x) + (1/9) = (1/3)... is that right? Change 1/3 to 3/9 so you have the two fractions with the same denominator. That leaves:
(2/x) + (1/9) = (3/9)
Then subtract the 1/9 from both sides:
(2/x) = (2/9)
Time both sides by x:
(2) = (2/9)x
Divide by (2/9) on both sides:
(2)/(2/9) = x
Simplify:
9 = x
