IN MATH: 1. n. a procedure for solving simultaneous equations; linear combination method. EX.

To solve a system of equations in 2 variables:

1st: Line up the variables in both equation, x above x, y above y, = above =, constant above constant.

2nd: (Optional) Multiply one or both equations so the coefficients of one variable are opposites.

3rd: Add the equations to eliminate one variable.

4th: Solve.

5th: Use this solution to solve for the other unknown.

6th: (Optional) Write answer as an ordered pair in alphabetical order.

IN ENGLISH: as defined above.

APPLICATION: See list 310.

1. To solve this system by the addition method, one might multiply the bottom equation by what number to eliminate the y?

      
         5x + 3y = 6
        10x -  y = 0
