WebJan 23, 2024 · A 3 variable system of equations is a set of equations that has three variables (i.e. x,y,z). In order to solve a 3 variable system of equations , there needs to be at least three equations. WebTake the solution (s) and put them in the original equation to see if they really work. Example: solve for x: 2x x − 3 + 3 = 6 x − 3 (x≠3) We have said x≠3 to avoid a division by zero. Let's multiply through by (x − 3): 2x + 3 (x−3) = 6 Bring the 6 to the left: 2x + 3 (x−3) − 6 = 0 Expand and solve: 2x + 3x − 9 − 6 = 0 5x − 15 = 0 5 (x − 3) = 0
