What is System of equation?
Inconsistent System
A system of equations to have no real solution, the lines of the equations must be parallel to each other.
Consistent System
1. Dependent Consistent System
A system of the equation to be Dependent Consistent System the system must have multiple solutions for which the lines of the equation must be coinciding.
2. Independent Consistent System
A system of the equation to be Independent Consistent System the system must have one unique solution for which the lines of the equation must intersect at a particular.
Let the number of multiple choice questions be represented by x, while the number of descriptive questions be represented by y. Therefore, the total questions can be written as,
x + y = 25
Solving for x,
y = 25 - x
The total score of Ronald can be written as,
3x + 8y = 150
3x + 200 - 8x = 150
-5x = -50
x = 10
Substitute the value of x in any one of the equation,
x + y = 25
10 + y = 25
y = 15
Hence, there were 10 multiple choice question, while 15 descriptive type questions.
