To find solutions from graphs, look for the point where the two graphs cross one another. This is the solution point. For example, the solution for the graphs \(y = x + 1\) and \(x + y = 3\) is the ...

You can use a SOLVE statement to solve the nonlinear equation system for some variables when the values of other variables are given. Consider the demand and supply model shown in the preceding ...

The unknown values in an equation could be the individual costs of a smoothie and a banana when the combined cost is known. Simultaneous equations can be useful when running a business. Watch the ...
