Question

Solve: 3/x+1/2=5/6
a. 12
b. 9
c. 6
d. 3

Answer 1

Hint, multiply the middle equation by 3/3

Answer 2

You'll end up with

\(\large\frac{3}{x} + \frac{3}{6} = \frac{5}{6}\)

Answer 3

Now we can subtract 3/6 from both sides to get:

\(\frac{3}{x} = \frac{5}{6} - \frac{3}{6}\)

Answer 4

9!

Answer 5

Combining fractions on the right side we get:

\(\frac{3}{x} = \frac{2}{6}\)

Answer 6

Simplifying the right side we get

\(\frac{3}{x} = \frac{1}{3}\)

Answer 7

Cross multiplying we get

x = 9
