Equations such as 3𝑥 + 8 = 15 need two steps. Make sure you are confident in calculating with negative numbers, which is a skill often needed to solve equations.

Solving Linear Systems (SymPy) Most linear algebra courses start by considering how to solve a system of linear equations.

By harnessing randomness, a new algorithm achieves a fundamentally novel — and faster — way of performing one of the most basic computations in math and computer science.

For example, if you scan a linear equation asking you to solve for x, like “x-4=10,” the results will include links to online tutorials or even YouTube videos explaining how to solve similar ...
