AUGMENTED MATRIX METHOD TO SOLVE SYSTEM OF LINEAR EQUATIONS (Precalculus, Section 9.7)
For the following exercises, write the augmented matrix for the linear system.
8x−37y=8 2x+12y=3
2x−3y=−95x+4y=58
6x+2y=−43x+4y=−17
2x+3y=12 4x+y=14
For the following exercises, solve the system by Gaussian elimination.
100030
124536
-20 0211
6234-4-17
-4-33-5-2-13
3 4-6-8 12-24

For the following exercises, set up the augmented matrix that describes the situation, and solve for the desired solution.
Every day, a cupcake store sells 5,000 cupcakes in chocolate and vanilla flavors. If the chocolate flavor is 3 times as popular as the vanilla flavor, how many of each cupcake sell per day?
At a competing cupcake store, $4,520 worth of cupcakes are sold daily. The chocolate cupcakes cost $2.25 and the red velvet cupcakes cost $1.75. If the total number of cupcakes sold per day is 2,200, how many of each flavor are sold each day?
You invested $10,000 into two accounts: one that has simple 3% interest, the other with 2.5% interest. If your total interest payment after one year was $283.50, how much was in each account after the year passed?
