Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Equations such as 𝑥 – 5 = 12 need one step to solve. Equations such as 3𝑥 + 8 = 15 need two steps. Make sure you are confident in calculating with negative numbers , which is a skill often ...

Linear relationships can be expressed either in a graphical format or as a mathematical equation of the form y = mx + b. Linear relationships are fairly common in daily life.

You might have millions of variables and millions of equations, but each equation might only involve a small number of the overall variables. These types of linear systems are called “sparse,” ...

Capture relationships between data sets by graphing linear equations in Microsoft Excel 2007. Linear equations allow you to predict values within your data set and view the overall trend.

Quantum information researchers have tried to use linear equations as a key to unlock nonlinear differential ones for over a decade. One breakthrough came in 2010, when Dominic Berry , now at ...

Key points about one- and two-step linear equations ... Show answer Hide answer. 𝑤 = 6. To solve the equation, do the inverse operation. The inverse of subtracting 8 is adding 8.
