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.

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

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.
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
usually in the problem it will say of
remedy, solve

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

Algebra was invented by the Muslim mathematician Al-Khwarizmi and is the Arabic word (aljabr) for "equation".
