GO Consistent and Inconsistent Systems of Equations All the systems of equations that we have seen in this section so far have had unique solutions. These are referred to as Consistent Systems of Equations, meaning that for a given system, there exists one solution set for the different variables in the system or infinitely many sets of solution.
Number of solutions algebra Video transcript We're asked to use the drop-downs to form a linear equation with no solutions.

Question the equation for line m is y = 1/2x use this information and these descriptions to write an equation for line n, line p, and line r. I am totally lost on this. Line m and line n have no solutions. write an equation that can represent line n. Line m and line p have infinitely many solutions. If by a system of equations you want two "different" equations with infinitely many points (solutions) in common you could take any linear equation like the one Hamilton gave you y = x + 1 and multiply it by 2 to get 2y = 2x + 2.
So a linear equation with no solutions is going to be one where I don't care how you manipulate it, the thing on the left can never be equal to the thing on the right. And so let's see what options they give us. One, they want us to-- we can pick the coefficient on the x term and then we can pick the constant.
So if we made this negative 11x, so now we have a negative 11x on both sides. Here on the left hand side, we have negative 11x plus 4. If we do something other than 4 here, so if we did say negative 11x minus 11, then here we're not going to have any solutions.
And you say, hey, Sal how did you come up with that? Well think about it right over here.
We have a negative 11x here, we have a negative 11x there. If you wanted to solve it algebraically you could add 11x to both sides and both of these terms will cancel out with each other and all you would be left with is a 4 is equal to a negative 11, which is not possible for any x that you pick.
Another way that you think about it is here we have negative 11 times some number and we're adding 4 to it, and here we're taking negative 11 times that same number and we're subtracting 11 from it. So if you take a negative 11 times some number and on one side you add four, and on the other side you subtract 11, there's no way, it doesn't matter what x you pick.
There's no x for which that is going to be true. But let's check our answer right over here.A system of equations has infinitely many solutions if there are infinitely many values of x and y that make both equations true. A system of equations has no solution if there is no pair of an x-value and a y-value that make both equations true.
Writing equations with a given number of solutions - Example Write a linear equation in one variable that has no solution. Since we want to write a linear equation in one variable that has no solution, let us start with a false statement such as 5 = 7.

A System of Linear Equations is when we have two or more linear equations working together.
