2 algebra questions

since i have to fill up the minimum 100 characters even though the questions arent that complex ill just write a summary! 🙂

• Write and use systems of linear equations to solve problems
• Solve systems of linear equations using graphs, tables of values, substitution, elimination, and matrices
• Use linear programming to solve real-world problems such as ones concerned with maximizing profit or minimizing cost
• Solve systems of linear inequalities by graphing, including absolute value inequalities

questions below

Solve the system using an augmented matrix. Show all work.
S-x-3y=-17
12x-6y=-26
Note: Remember to show all of the steps that you use to solve the problem. You can use the
comments field to explain your work. Your teacher will review each step of your response t
ensure you receive proper credit for your answer.
What is the solution to the following system of equations?
3x + 2y + 2 = 7
5x + 5y + 4z 3
3x + 2y + 32 = 1
=
