Select the range of cells as per the matrix A layout such as C10: E12.To find the inverse of matrix A ( A -1 ) we need to use the MINVERSE function as follows In matrix notation form we can write it as Īnd to find the value of unknown variables X we need to find the inverse of matrix A ( A -1 ) and multiply it with matrix B, such as To solve equations using functions we need to set up the data as follows įigure 2. Suppose we have three equations in our system of equations in our example. We can solve the system of equations by using MINVERSE and MMULT mathematical functions.

How to Solve the System of Equations Using Excel Functions To solve the system of equations, we can utilize functions and the equation solver tool.įigure 1. In mathematical terms, the system of equation is set of two or more equations having the same set of unknown variables like x, y, z where we need to find the values of unknown variables to solve these equations. Graphing is easy, you just plot both lines and find where the two intersect, it's also the most difficult to find the exact answer because you'll have to eyeball it a bit and draw really neatly.How to Solve the System of Equations in Excel So now you have one equation in one unknown, and can solve for y, and once you have y, go back to the first equation and plug in so you can solve for x 𝛢𝛼 𝛣𝛽 𝛤𝛾 𝛥𝛿 𝛦𝜀𝜖 𝛧𝜁 𝛨𝜂 𝛩𝜃𝜗 𝛪𝜄 𝛫𝜅 𝛬𝜆 𝛭𝜇 𝛮𝜈 𝛯𝜉 𝛰𝜊 𝛱𝜋 𝛲𝜌 𝛴𝜎 𝛵𝜏 𝛶𝜐 𝛷𝜙𝜑 𝛸𝜒 𝛹𝜓 𝛺𝜔įor elimination you're trying to scale one or both of your equations by some factor so when you add the two equations together, one of the variables disappears, for your example, multiply all terms in the top equation by 2 and the bottom equation by -3 and add the two equations together and the x varible cancels out leaving only one equation and one variable, once you've solve for y, you can go back to either one of your equations, replace y with what you solved for, and then solve for xįor substitution, you take one equation and solve for one of the variables, putting the variable on one side and the other variable and constant term on the other, for your example, solve the top equation so x = -6y + 23 now you know what x equals, so in your second equation, wherever you see an x replace it with -6y + 23, so you get
