Linear Equation Calculator

Enter the variables a, b, and y into the calculator below. The linear equation calculator will evaluate and solve for the missing variable x.

Linear Equation Formula

A linear equation is a term used in mathematics to describe a linear line in the form:

Where xn are variables, also known as indeterminates, and a and b are coefficients or constants. These constants can sometimes be considered parameters of the equation. That is since they do not vary, having known constants can produce a solid line when extrapolated across all x values.

It’s also possible to think of a linear equation as a linear polynomial over a field. The solution to that polynomial are such that the value of the equation is true or 0. When there is only one variable, such is the case with the linear equation y=mx+b. The solution to that equation yields coordinate points in the Cartesian plane. Since there are two variables in the equation, there are two solutions, which equations to both the x and y intercept of that line.

How to find the unknown variable in a linear equation?

We will now go over an example of how to calculate the unknown variable in a linear equation.

  1. The first step is to set up your equation, for this we will assume the form of the equation to be y=ax+b, but in reality the equation can have an infinite number of variable, such as y=ax+cz+b. In that case you would need to know two known variables in order to find the missing value, but back on to our example.
  2. The next step is to find the known values. When looking at a line in the form y=ax+b, both a, b, and y are known. For this example we will say the values are 1,2, and 3 respectively.
  3. Next, we must manipulate the equation in order to have x on one side. After some manipulation we find that x=(y-b)/x.
  4. Finally, enter the known values into the equation to solve for x. x=(3-2)/1 = 1. Our unknown variable is 1.
  5. Analyze the results and apply to additional problems.

It’s extremely clear that solving for an unknown variable in a equation is as simple as manipulating the equation so that the unknown variable is on one side, then entering the constants.
