Choose based on the learning interaction, then check whether you can solve a similar problem without the tool. An explanation is useful when it helps you learn a method rather than simply produce an answer.
Chalkline's listing describes question-led tutoring from photographed problems and worked analogies. It states that full worked solutions in the app are available through a parent or teacher unlock.

Solving a linear equation means keeping both sides equal while isolating the unknown. Set up an equation, try a value of x and inspect each side. Reveal the worked explanation when you want to compare your reasoning with the algebra.
The lab uses equations of the form a×x + b = c. The graph and values respond to your inputs; no photograph is uploaded and no general homework-solving service is called.
Inputs are processed in this page. Nothing is submitted to the app or a business. Download a result to keep it; this page does not automatically save your work.
For 3x + 4 = 19, trying x = 4 gives 16 on the left and 19 on the right. Subtracting 4 from both sides leaves 3x = 15; dividing by 3 gives x = 5, which checks in the original equation.
