x = 1 y = 2 Solving By Elimination 12x 7y = 2 8x 11y = 30 First, let's have a look at our system and recall what the elimination method is To eliminate a variable (either x or y), we have to multiply the different equations in the system to get the least common multiple One equation must be positive and the other negative to cancel each other out The least common multiple ofSo, we have one equation and two variables It means that x can be any number and y a number sucAnswer (1 of 5) When you get deeper into algebra, you'll start applying the word "function" differently At first, you always look at the representation and try to express y in terms of x Then you look at the result and decide if each xvalue used maps to only one y
