Solve two-step equations without fractions in the starting question. Questions include forms such as 2x + 3 = 6, −4x − 5 = 20, and 5 − x = 8.

Step 0
Note: dividing by zero is blocked because it is undefined. Multiplying by zero is allowed as a demonstration, but the program warns that it destroys the information about the original value of x. New random questions include positive and negative solutions and starting equations with x first or the constant first.
