Probably the most important key for this is the CALC key (just below the SHIFT key). For full details, please refer to the "Using CALC" section in the manual. If you've misplaced the manual, you can download it (and the Appendix) from http://support.casio.com/manualfile.php?rgn=1&cid=004001004

How can i write this in my calculator example. 2x=10 the answer is x=5 but how can i put x in the calculator


What you want to do is solve the linear equation 2x=10 to find the value of the unknown x that makes the equality true. Solving an equation usually involves rearranging therms, factors and so on. However your calculator was not designed to handle the solution of equations, no matter how simple they are.
Some Casio scientific calculators can solve some types of equations (polynomials of degree 2 or 3, simultaneous linear equations in up to 3 unknowns). These are the FX-115 ES (Plus) and FX-991 ES (Plus C). Other equivalent models are sold in the world under different names.

Sorry, the Fx-115W is unable to solve equations of any type. In addition to that, the more sophisticated Casios such as the FX-991 ES solve linear equations of no more than 3 variables.

How to solve equations with two variables by usin CASIO fx901 calculater? eg- 6x+9y=2700 5x+4y=1560


The FX-901 calculator seems to be the equivalent of the FX 260 Solar sold in North America. It does fraction calculations, permutation, statistics but lack the Equation Solver.
You cannot use it to solve equations.
Casio Scientific calculators that can handle equation solving are the FX-115 and FX-991.
Simplify your first equation by dividing all its terms by 3, then use elimination to carry out the solution by hand.
