Linear Algebra

Linear systems are a combination of variables and coefficients they look like this:

a_1x_1 + a_2x_2 + a_3x_3 ... a_nx_n

Where a_1...a_n are the coefficients.

Linear equations are almost the same but with an equal sign and a constant on the right side like this.

a_1x_1 + a_2x_2 + a_3x_3 ... a_nx_n

We want to solve these by finding real numbers for x_1 ... x_n that satisfy the equation.
