WebOct 6, 2024 · In order to solve systems of equations in three variables, known as three-by-three systems, the primary tool we will be using is called Gaussian elimination, named after the prolific German mathematician Karl Friedrich Gauss. WebOct 6, 2024 · A linear equation with three variables20 is in standard form if ax + by + cz = d where a, b, c, and d are real numbers. For example, 6x + y + 2z = 26 is in standard form. Solving for z, we obtain z = − 3x − 1 2y + 13 and can consider both x and y to be the independent variables.
