Unformatted text preview: Select a variable to eliminate, say y . The coefficients of y are 5 and 2. These both divide into 10. Arrange so that the coefficient of y is 10 in one equation and 10 in the other. To do this, multiply the top equation by 2 and the bottom equation by 5. Add the new equations, eliminating y . Solve for the remaining variable. Substitute for x and solve for y . Check the solution in the original equation. These are both true statements. The solution is . If the elimination method produces a sentence that is always true, then the system is dependent, and either original equation is a solution. If the elimination method produces a sentence that is always false, then the system is inconsistent, and there is no solution....
