1 8x 1 2 1 4 LCD8 1 8 x 1 2 1 4 L C D 8. This clears the fractions. Subtract 16 from both sides.

Find the LCD of the fractionsin this case 6. X 3 x 16 5 b If you had multiplied. Properties of Real Numbers.

But if you want to get rid of fractions in an equation you can multiply both sides of the equation by the least common multiple of the fractions. Examples Clear the fractions and solve the equations. To clear a fraction from an equation multiply all of the terms on both sides of the equation by the fractions denominator.

Then to solve the last step is to isolate the variable by dividing both sides by 12. Virtual Nerds patent-pending tutorial system provides in-context information hints and links to supporting tutorials synchronized with videos each 3 to 7 minutes long. A Multiply each term by 3.

81 8x 1 281 4 8 1 8 x 1 2 8 1 4 Use the Distributive Property. This alternate method eliminates the fractions. The left-hand side of the equation just becomes-- you have this 3x here.

I am not entirely sure what you mean with clear. Plus if the number does a good enough job cleaning up the fractions maybe well see how it does with our bedroom. To solve this equation we have to multiply both sides by the denominator to get rid of the fraction.
