The table given below explains the situations where we have exactly one solution, more than one solution and infinitely many solutions for a linear equation in one variable.

If we can solve the equation and get something like x=b where b is a specific number, then we have one solution. If we end up with a statement that's always false, like 3=5, then there's no …

Jul 28, 2025 · Below, I will explain methods for the most common types of equations—especially algebraic equations like linear, quadratic, and higher-degree polynomials—and general …

Oct 22, 2025 · Learn how to tell if a system of equations has one, no, or infinite solutions. This SAT Math guide explains patterns and strategies to solve these problems confidently.

You've probably been solving a lot of equations that end with a variable equaling something (ex: x = 4). But what if when you solve your equation, you end up with something like 4 = 4 or x =...

When we consider a system of linear equations, we can find the number of solutions by comparing the coefficients of the variables of the equations. Also, we can find the number of …

If there is one solution, one x is left in the equation. If the simplified equation has no variables left, then there are either no solutions or infinitely many solutions.

Quite frankly, we don’t always need the exact values of solutions; sometimes, we just need to know how many there are. For example, we may want to know if the related graph intersects …

To determine how many solutions a system of equations has, we need to analyze the equations. If you provide the specific system of equations, I can help you determine the number of solutions.

Use the textbox below to record how many steps you think it will take before you can tell whether there is no solution or one solution. First, distribute the 3 into the parentheses on the right …
