Linear equations calculator


This linear equations calculator will solve any linear equations of the form ax + b = c.

Guidelines:

Do not enter any number with a slash "/ "!

Starting from left to right, the first box is a, the second box is b, and the last box is c

Enter 1 for a is the equation has the form: x + b = c. For example, x + 2 = 5

Enter 0 for b is the equation has the form: 2x = c. For example, 2x = 6

If your equation has the form 2x − b = c, you know it means the same thing as 2x + -b = c.Therefore, enter -b in the second box

If your equation has the form 2x − -b = c, you know it means the same thing as 2x + b = c.Therefore, enter b in the second box


            a                       b                   c
       x   +      =   


                    

       x =     


Scenarios:

For x + 2 = 5, enter a = 1, b = 2, and c = 5

For x + -3 = -5, enter a = 1, b = -3, and c = -5

For x − 3 = 5, enter a = 1, b = -3, and c = 5

For 2x + -2 = 6, enter a = 2, b = -2, and c = 6

For -2x − 2 = 6, enter a = -2, b = -2, and c = 6

For 2x = 6, enter a = 2, b = 0, and c = 6

For 2x − -2 = 10, enter a = 2, b = 2, and c = 10

You are responsible to solve linear equations on your own first. Then, this linear equations calculator will help you check your answers.
