# Algebra Problem Solving Examples

We know there are seven days in the week, so: d e = 7 And she trains 27 hours in a week, with d 5 hour days and e 3 hour days: 5d 3e = 27 We are being asked for how many days she trains for 5 hours: d Solve: The number of "5 hour" days is 3 Check: She trains for 5 hours on 3 days a week, so she must train for 3 hours a day on the other 4 days of the week.

3 × 5 hours = 15 hours, plus 4 × 3 hours = 12 hours gives a total of 27 hours So Joel’s normal rate of pay is \$12 per hour Check Joel’s normal rate of pay is \$12 per hour, so his overtime rate is 1¼ × \$12 per hour = \$15 per hour.

Many of us are familiar with the word problem, but are we aware of the fact and problems related to variables and constants?

When we say 5 it means a number but what if we say x=5 or 5y or something like that?

How long will it be before you and your sister have the same amount of money? Many students find solving algebra word problems difficult.Translating words to equations How to recognize some common types of algebra word problems and how to solve them step by step: Age Problems usually compare the ages of people.They may involve a single person, comparing his/her age in the past, present or future.Check There are now 16 boys and 12 girls, so the ratio of boys to girls is 16 : 12 = 4 : 3 At the start of the year there were 20 boys and 10 girls, so the ratio was 20 : 10 = 2 : 1 Consecutive means one after the other.And they are even, so they could be 2 and 4, or 4 and 6, etc.It could also be a time when you are trying to figure out if you were over charged for a bill.This is important stuff - when it comes time to spend YOUR money - you are going to want to make sure that you are getting paid enough and not spending more than you have to. let's put all this newly learned knowledge to work.

Example solve for x 2xx − 3 + 3 = 6x − 3 x≠3 We have said x≠3 to avoid a division by zero. Let's multiply through by x − 3 2x + 3x−3 = 6. Bring the 6 to the left 2x + 3x−3 − 6 = 0. Expand and solve 2x + 3x − 9 − 6 = 0. 5x − 15 = 0. 5x − 3 = 0. x − 3 = 0 That can be solved by having x=3. Let us check…

Below are more complicated algebra word problems Example #6 The ratio of two numbers is 5 to 1. The sum is 18. What are the two numbers? Solution Let x be the first number. Let y be the second number x / y = 5 / 1 x + y = 18 Using x / y = 5 / 1, we get x = 5y after doing cross multiplication Replacing x = 5y into x + y = 18, we get 5y + y = 18 6y = 18 y = 3…
