I hope all of the methods mentioned above for solving simultaneous equations in Excel will prompt you to apply them more effectively. We have provided a Practice section on the right side of each sheet so you can practice yourself. Then, add or subtract the two equations to eliminate one of the variables. Read More: How to Solve Nonlinear Equations in Excel (with Easy Steps) To solve a system of equations by elimination, write the system of equations in standard form: ax + by c, and multiply one or both of the equations by a constant so that the coefficients of one of the variables are opposite. Thirdly, follow the detailed steps described in Method 2.Įventually, your output should look like the image given below.Secondly, navigate to the Data tab > click the Analyze drop-down > choose the Solver option.Likewise, repeat the same process for the other two equations. Here, the D10, D11, and D12 cells indicate the Initial Values of X, Y, and Z. Firstly, proceed to the C11 cell and enter the C6 cell reference.Here, we’ll employ Cramer’s rule to solve the 3 linear equations with 3 unknowns, so, just follow these simple steps. Method-3: Solve Simultaneous Equations with 3 Variables Applying Cramer’s RuleĬramer’s rule is a formula in linear algebra for solving a system of linear equations with multiple unknowns.
