Now you need to enter the following array formula in cell D13.Įxcel 365 subscribers enter the formula in cell D13 and press enter. The constants are entered in cell range F8:F10. Continue with the remaining variables and equations until all numbers have been extracted. The number before the x variable in the first equation goes to cell C8, in this example 0.5 is entered in cell C8.Ĭontinue with the second equation which is 4, enter 4 in cell C9. Cell range C3:C5 contains three equations with variables x, y and z.įirst, extract the numbers from these three equations.

The image above shows how to solve three simultaneous equations with three variables using one Excel formula. Press with left mouse button on "OK" button to dismiss the dialog box.īack to top Solve linear equations using Excel formulas The following dialog box appears if a solution is found.ĭeselect checkbox "Return to Solver Parameters Dialog" if you are happy with the solution. Press with left mouse button on "Solve" button. The Solver dialog box now looks like this, see image below. Change "Select a Solving Method:" to "Simplex LP".Repeat steps 6 to 10 using cells C4 = D4 and C5 = D5.Press with left mouse button on "OK" button.The dialog box now looks like this, see image below.
Now do the same thing with the constants, however, move them to the right side of the equation.Ġ.5x + 2y - 1.5z = -2 Solve linear equations using Solver To move the variables on the right side to the left side add or subtract the variables based on their sign on both sides. The examples below are easier to follow if you convert the equations to standard form. This means that the variables are on the left side and the constant is on the right side of the equation.Įxample, the following equation is not standard form: 4 - 1.5z = -0.5x - 2y + 2 How to convert equations to standard form?
