If it has to do with a chapter on Rational Expressions and Equations, the the equation is ''work rate'' x ''time'' = ''work done''. Just substitue the information from the problem and voila! , you get your answer! Don't forget to put the stuff, like minutes or hours.

"Solve",
There was no word problem, so it would be a null equation.

Simultaneously? Multitasking?
Extraneous solutions turn up in a few different p;aces in algebra. One reason they turn up in logarithmic equations is that you can only have a log of a positive number, but when you solve the equation, one of the answers is negative. Did you ever do a word problem about a rectangle and have to solve a quadratic equation? You probably got 2 answers, and had to reject one of them because the length of a rectangle can't be negative. Same idea: the algebra doesn't understand what the problem is about, it just churns out answers!
After reading a word problem, u need to form an equation of which can sometime be difficult. After reading it, u may not know how to solve it anyways. There can be many hard steps.
remedy, solve
"Solve",
usually in the problem it will say of
Usually in algebra the term "unknown" is used for a variable ( commonly designated as x ) you are trying to solve for. For instance the mathematical expression 2 + x = 5 may be presented to the student as a problem. The answer is to solve for the unknown or x. The solution would be x = 3

You might, if your solving a word problem and the units were kilograms or milligrams.

The rules for solving word problems are read the problem, decide what you need to do, solve the problem, and check your answer.
