SAT Review Lesson 2: Using LCD to eliminate fractions in an equation (SAT Math review)

This video covers a helpful technique for eliminating fractions in an equation. Use the LCD by multiplying it across both sides of the equation and now your equation is easier to solve!

LCD is the least common denominator, and can be found by multiplying all the denominators together. (Sometimes, multiplying the denominators will give you a common denominator, but not the least common denominator, this just means you will have more simplification to do after you multiply every term by the common denominator.)
