Question
How many solutions does the system of linear equations have?
y = -2x + 4 and 7y = -14x + 28
- Exactly one solution
- No solutions
- Infinite solutions
- None of these
Hint:
When two or more linear equations interact, we have a system of linear equations. There are three systems of the equation:
- No solution: System with parallel lines
- One solution: System with intersecting lines
- Infinitely many solutions: System with coinciding lines
Here in this question, we have given two equations where we have to find which system it belongs to and how many solutions it has.
The correct answer is: Infinite solutions
The value or values that hold true for each equation in the system constitute the solution to the system of equations. In this question we have given two equations, those are:
We have to find how many solutions It has. Let's first re-arrange the terms, we get:
So these equations have an infinite number of solution.
So here we have given two equations, y = -2x + 4 and 7y = -14x + 28 and we had to find out how many solutions it have. Using the concept we found out that the system is having intersecting lines and hence it has an infinite number of solution.
