Solving systems of 3 linear equations
WebFeb 1, 2024 · x 4 = 2 x 1 + 2 x 3 = − 10 x 3 = − 9 + x 2. Finally subtract the last one multiplied by two from the second equation. x 4 = 2 x 1 = 8 − 2 x 2 x 3 = − 9 + x 2. Now it's clear that your system has an infinite number of solutions (one per each value given to x 2 ). This is not surprising since you have four variables and just three equations. WebOct 11, 2024 · Example 3: Solve System of Equations with Four Variables. Suppose we have the following system of equations and we’d like to solve for the values of w, x, y, and z: 6w + 2x + 2y + 1z = 37. 2w + 1x + 1y + 0z = 14. 3w + 2x + 2y + 4z = 28. 2w + 0x + 5y + 5z = 28. To solve this system of equations, we can first type in the following values in Excel:
