QED Solver
Equations, plots, and the systems that do not come out neatly. Type the problem, solve it, and keep it. The three lines are a whole problem, if you would rather start from one that already works.
Try this one
2a + 3b + 7c = 9 7a - 8b - 2c = 11 3a + 5b - 4c = 7
Three equations, three unknowns. Open it and solve.
A blank page for the problem in front of you. It stays with your other work.
One short page, with the problem actually running beside the explanation.
Post the lines, or a problem that is already solved, and ask what you are missing.
