Answer:

Step-by-step explanation: There are three possible solutions for a linear equation: no solution, one unique solution, and infinitely many solutions.

A linear equation is an algebraic equation in which the highest exponent of the variables is 1. For example, 2x + 3 = 5 is a linear equation because the highest exponent of the variable x is 1.

If a linear equation has no solutions, this means that the equation is contradictory and there is no possible value of the variable that can make the equation true. For example, the equation 2x + 3 = 5 has no solutions because it is already true for all possible values of x.

If a linear equation has a unique solution, this means that there is only one possible value of the variable that can make the equation true. For example, the equation 2x + 3 = 5 has a unique solution because there is only one value of x that can make the equation true (in this case, x = 1).

If a linear equation has infinitely many solutions, this means that there are an infinite number of possible values of the variable that can make the equation true. This typically happens when the equation has the form of 0 = 0, which is always true for any value of the variable. For example, the equation 0 = 0 has infinitely many solutions because it is true for all possible values of x.

In general, you can tell whether a linear equation has no solutions, a unique solution, or infinitely many solutions by solving the equation. Solving a linear equation involves isolating the variable on one side of the equation and then using algebraic techniques to find its value. If you are able to find a unique value for the variable, then the equation has a unique solution. If you are unable to find a unique value for the variable, then the equation either has no solutions or infinitely many solutions.
