... Looking at the x-terms: The least common multiple of 4x and 5x is 20x . We could multiply the first equation by 5 so that it contains the term 20x , and multiply the second equation by 4 so that it contains the term −20x . Looking at the y-terms: The least common multiple of 3y and 6 y is 6 y . We c ...

The Systems and Applications of the Systems
... You can use the Addition and Subtraction Properties of Equality to solve a system by using the elimination method. Step 1. Decide which variable you wish to eliminate. Step 2. Multiply each equation by a number that will make the coefficients of the chosen variable the same in value but opposite in ...
