Linear equation example

Solve 3(x - 2) = 15 for x. Explain each equality-preserving step, then substitute the result into the original equation to check it.

The complete walkthrough

  1. Review the equation

    Open Solver and keep the brackets, signs and equality exactly as written in the example.

  2. Ask for the reasoning

    Choose Work through problem. The request includes the instruction to explain each step and check the value.

  3. Check by substitution

    Compare the returned steps with the original equation, then verify the value on both sides.
