Solve linear equations in two variables
WebSelect 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.
