WebOct 6, 2024 · Just as with linear systems with two variables, not all linear systems with three variables have a single solution. Sometimes there are no simultaneous solutions. Example 3.4.5: Solve the system: { 4x − y + 3z = 5 21x − 4y + 18z = 7 − 9x + y − 9z = − 8. Solution. In this case we choose to eliminate the variable y. WebLet's solve a few more systems of equations using elimination, but in these it won't be kind of a one-step elimination. We're going to have to massage the equations a little bit in order to prepare them for elimination. So let's say that we have an equation, 5x minus 10y is equal to 15. And we have another equation, 3x minus 2y is equal to 3.
