It is reasonably simple. You first want to make each word which is relavent to find out the answer a letter. An example of this could be a common example in chemistry in which you are given current and time. From this you would want to find the amount of charge or coloumbs, make charge a letter such as I and time one such as T. Using an Equation you can work out that Q (Charge)=IxT. So just times those two together and there you have your answer via using an equation.

you can write seven billion either worded or as numbers here are some examples: seven billion or 7,000,000,000
Algebra
Equations are not especially useful for solving most of the real-life problems that people face, which is too bad, since problems that can be reduced to equations are likely to be solved before long if not immediately. However, there are many problems in the physical sciences and engineering that lend themselves to mathematical modeling and equations and modern computer allow many difficult computations to be made quickly. Statistical methods and computer simulations can solve problems where precise equations can not be found. Also, the mental discipline developed in learning any sort of mathematics will help you develop reasoning skills that will help you solve many real life problems in the future.
IF they are math related, write appropriate equations and then apply math rules to solve the equations.
Worded problems are paragraph-long math problems. instead of just setting up the answer for you, you have to read the "everday life problem", figure out how to set it up, then solve it.
poorly worded, try again

It may be possible to solve equations. Expressions cannot be solved until they are converted, with additional information, into equations or inequalities which may have solutions.
