Select any two integers between -12 and +12 which will become solutions to a system of two equations.

Write two equations that have your two integers as solutions. Show how you built the equations using your integers. Your solution and equations should not be the same as those of other students or the textbook. There are infinite possibilities.

Solve your system of equations by the addition/subtraction method. Make sure you show the necessary 5 steps.

**MathMate**, Wednesday, February 9, 2011 at 9:55pmI will try it with x=20, y=15

From this, you can supply coefficients and calculate the right hand side from the given values of x and y.

I choose coefficients 2 and -3 to give

2x-3y=2*20-3*15=-5

I choose again coefficients, 3 and -1 to give

3x-y=3*20-1*15=45

So my equations are

2x-3y=-5

3x-y=45

Then I would proceed to solve for x and y, which should give me x=20 and y=15, as expected.
