Types of Linear Equations:
S. No. | Types of Linear Equation | General form | Description | Solutions |
1. | Linear Equation in one Variable | ax + b = 0 | Where a ≠ 0 and a & b are real numbers | One Solution |
2. | Linear Equation in Two Variables | ax + by + c = 0 | Where a ≠ 0 & b ≠ 0 and a, b & c are real numbers | Infinite Solutions possible |
3. | Linear Equation in Three Variables | ax + by + cz + d = 0 | Where a ≠ 0, b ≠ 0, c ≠ 0 and a, b, c, d are real numbers | Infinite Solutions possible |
Simultaneous System of Linear Equations: A pair of equations in the format:
a1x + b1y + c1 = 0
a2x + b2y + c2 = 0
This arrangement is visually depicted through the use of two straight lines on the Cartesian plane, as explained in the following context:
When there is a unique solution then
x/(b1c2 - b2c1) = y/(c1a2 - c2a1) = 1/(a1b2 - a2b2)
This formula can be remembered as the diagram given below

The eligibility age criteria for class 10th CBSE is 14 years of age. Since your son will be 15 years of age in 2024, he will be eligible to give the exam.
That totally depends on what you are aiming for. The replacement of marks of additional subjects and the main subject is not like you will get the marks of IT on your Hindi section. It runs like when you calculate your total percentage you have got, you can replace your lowest marks of the main subjects from the marks of the additional subject since CBSE schools goes for the best five marks for the calculation of final percentage of the students.
However, for the admission procedures in different schools after 10th, it depends on the schools to consider the percentage of main five subjects or the best five subjects to admit the student in their schools.
