1. Problem Description
The problem is to solve the given system of linear equations:
(1)
(2)
And then describe the system of equations.
2. Solution Steps
We can solve the system of equations using either substitution or elimination. Let's use elimination. Multiply equation (1) by 5 and equation (2) by 2 to eliminate .
(3)
(4)
Subtract equation (4) from equation (3):
Substitute into equation (1):
So the solution is and . The solution to the system is .
The system is independent and consistent because the two lines intersect at one point.
3. Final Answer
The solution to the system is (-3, 4).
The equations are independent and consistent. Their graphs intersect at one point.
