Excel General; solving for 2 unknowns using 2 simultaneous equations; Results 1 to 2 of 2 solving for 2 unknowns using 2 simultaneous equations. What is y? A case of no solution means that the two lines never intersect; such lines are parallel to each other. So far in the study of algebraic equations, we have looked at solving single equations with only one variable. I did its fitting using Excel and got an equation. For a system of equations with 2 unknowns, you need two equations to solve the system. What happens if there is more than one variable in an equation? Jul 25th 2012 #1; Hi, I've looked in this and other forums, and while there are many topics on solving simultaneous equations, I could not find an example similar to what I'm trying to do. Solve Cubic Equation in Excel using Goal Seek. And in that discussion, we noted that substitution in a way is kind of a limited value. For example something like 2x + 7 = 15.
