If the same number is added to both sides of an equation, the results on each side are equal in value. We can restate it in symbols this way. For real numbers a, b, c if a=b thenat+tc=b+ec Here is an example. If3=6/2, then3+5=6/2+5 ...

To solve the nonlinear system of equations exp(−exp(−(x1+x2)))=x2(1+x21)x1cos(x2)+x2sin(x1)=12 using the problem-based approach, first define x as a two-element optimization variable. Get x = optimvar('x',2); Create the first equation as an optimization equality expression...
The equations section of QuickMath allows you to solve and plot virtually any equation or system of equations. In most cases, you can find exact solutions to your equations. Even when this is not possible, QuickMath may be able to give you approximate solutions to almost any level of accura...
Solve the equation exp(log(x)log(3x))=4. By default, solve does not apply simplifications that are not valid for all values of x. In this case, the solver does not assume that x is a positive real number, so it does not apply the logarithmic identity log(3x)=log(3)+log(x). As...
