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?

If this had not been done for you, you might have written it like this:.

    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…
