Solving Linear Equations Containing Fractions

Solve:

Solution First, find the LCD of the fractions. Step 1 Factor each denominator into its prime factors. Step 2 List each factor the greatest number of times that it appears in any one of the denominators. Step 3 Multiply the prime factors in the list. So, the LCD of the fractions is 40.	8 = 2 Â· 2 Â·2 20 = 2 Â· 2 Â· 5 10 = 2 Â· 5 2, 2, 2, 5 2 Â· 2 Â· 2 Â· 5 = 40
Next, clear the fractions:
â€¢ Multiply each side by the LCD, 40.
â€¢ Simplify.	5x = 2x - 4
Then, solve the equation for x: â€¢ Subtract 2x from both sides.	3x = -4
â€¢ Divide both sides by 3. We leave the check to you. The solution is .
