Excel can solve equations through several of its mathematical functions, but the single Excel tool that works on the largest variety of equations is the program's Solver Add-in. This tool reads an ...

For example, consider the problem of solving three simultaneous equations: These equations can be written in matrix form as The PRINT option of the RESET command causes automatic printing of results.

Most linear algebra courses start by considering how to solve a system of linear equations. \[ \begin{align} a_{0,0}x_0 + a_{0,1}x_0 + \cdots a_{0,n-1}x_0 & = b_0 ...

But a new proof establishes that, in fact, the right kind of guessing is sometimes the best way to solve systems of linear equations, one of the bedrock calculations in math. As a result, the proof ...

To solve an equation, the value of the unknown variable needs to be found. It can be found by performing the same operation on each side of the equation until the value for \(x\) is known.

By Kenneth Chang and Jonathan Corum The quadratic equation has frustrated math students for millenniums. But a math professor at Carnegie Mellon University in Pittsburgh may have come up with a ...
