# Solving Equation Word Problems

You can figure out Two planes, which are 2400 miles apart, fly toward each other. At the end of one interest period, the interest earned was \$50. The interest rate for the \$5000 investment is greater than the interest rate for the \$5000 investment. Let x be the interest rate for the \$7000 investment.

Then the interest rate for the \$5000 investment is .

In the example, the question asks how many socks the sisters own together, so you can disregard the information about Mark. This eliminates much of the information and leaves you with only the total number of socks that the sisters started with and how many the little sister lost. For example, the words and phrases "sum," "more than," "increased" and "in addition to" all mean to add, so write in the " " symbol over these words.

Use a letter for the unknown variable, and create an algebraic equation that represents the problem.

Once you identify the problem, you can determine the unit of measurement for the final answer.

In the following example, the question asks you to determine the total number of socks between the two sisters.

While the degree of difficulty may change, the way to solve word problems involves a planned approach that requires identifying the problem, gathering the relevant information, creating the equation, solving and checking your work.

Begin by determining the scenario the problem wants you to solve. Either way, the word problem provides you with all the information you need to solve it.

Word problems often confuse students simply because the question does not present itself in a ready-to-solve mathematical equation.

You can answer even the most complex word problems, provided you understand the mathematical concepts addressed.
