Linear Equations




A linear equation is one where all the variables (unknowns) are only raised to the first power.

x+1=10\;\quad\text{is\;a\;linear\;equation}

x^{2}+1=10\quad\quad\text{is\;not\;a\;linear\;equation}

Linear equations can also have multiple variables, like: x-2y=8.

Algebra questions on the COMPASS Test cover linear equations in both one and two variables. We’ll cover these cases in two separate lessons.
