How to solve 3 unknowns with 2 equations
WebOct 6, 2024 · Determine whether the ordered triple ( 3, − 2, 1) is a solution to the system. x + y + z = 2 6 x − 4 y + 5 z = 31 5 x + 2 y + 2 z = 13 Solution We will check each equation by … WebAnd we could do that, we can essentially create two equations with two unknowns. The two unknowns will be y and z. If we can pair up these equations and eliminate x with each of these pairings. So for example, we can pair these first two. We can pair the last two. And that's all we would need to have to eliminate the x's and still have two ...
