Use elimination to solve the system of equations: -6x - y = 30 and 4x + 6y = 12 Use elimination to solve the system of equations: x + 8 y = 3 4 x - 2 y = 7. Use elimination to solve the system of equations. 3x - 6y = -3 2x + 4y = 30 Solve the following systems...
One of the last examples onSystems of Linear Equationswas this one: Example: Solve x + y + z = 6 2y + 5z = −4 2x + 5y − z = 27 We went on to solve it using "elimination", but we can also solve it using Matrices!
1. **方程调整**:将第一个方程 \(2x + 3y = 1\) 乘以 2,得到 \(4x + 6y = 2\)。 2. **消元**:用新方程减去第二个方程 \(4x + 2y = 7\): (4x + 6y) - (4x + 2y) = 2 - 7 4y = -5 y = -5/43. **代入求解**:将 \(y = -\frac{5}{4}\) 代入原第一个方程 \...
Of course, Gaussian elimination works if we have a unique solution, but will this work for inconsistent or dependent systems? The short answer is no, it won't work. Why doesn't it work? What happens when we try to solve these types of systems using Gaussian elimination? Let's look ...
