Question

Solve the system of equations

2x + y = -1.5
y = 3.5x + 15
What is the solution to the system?
Enter your answer as an ordered pair, like this: (42, 53).
HINT:
Make sure the point is (x, y). The solution to a system of linear equations is where the
equations are equal. You can graph the equations in Desmos and find the intersection
point.
O (-3, 4.5)
O(4.5, -3)
O(-4,0)

Answer 1

Explanation:

Systems of linear equations can be used to solve resource allocation problems in business and economics (see Problems 73 and 76 in Section 4.3 on

production schedules for boats and leases for airplanes). Such systems can

involve many equations in many variables. So after reviewing methods for

solving two linear equations in two variables, we use matrices and matrix

operations to develop procedures that are suitable for solving linear systems of

any size.
