How To Solve Word Problems Using Equations

Ratio Problems require you to relate quantities of different items in certain known ratios, or work out the ratios given certain quantities.This could be Two-Term Ratios or Three-Term Ratios Symbol Problems Variation Word Problems may consist of Direct Variation Problems, Inverse Variation Problems or Joint Variation Problems Work Problems involve different people doing work together at different rates.Average Problems involve the computations for arithmetic mean or weighted average of different quantities.

We can have objects that Travel at Different Rates, objects that Travel in Different Directions or we may need to find the distance Given the Total Time Fraction Problems involve fractions or parts of a whole.

Geometry Word Problems deal with geometric figures and angles described in words.

Many students find solving algebra word problems difficult.

The best way to approach word problems is to “divide and conquer”.

Their difference = 48According to the question, 7x - 3x = 48 ⇒ 4x = 48 ⇒ x = 48/4 ⇒ x = 12Therefore, 7x = 7 × 12 = 84 3x = 3 × 12 = 36 Therefore, the two numbers are 84 and 36.3. If the perimeter is 72 metre, find the length and breadth of the rectangle.

More solved examples with detailed explanation on the word problems on linear equations.6. After 5 years, father will be three times as old as Robert. What is the minimum number of computer she needs to sell in a month to make a profit? Well, we can do a little bit of long division to handle that. So I'll let you think about that for a second. So we have x on our right-hand side is going to be equal to 10,000/27. Consecutive Integer Problems deal with consecutive numbers.The number sequences may be Even or Odd, or some other simple number sequences.Break the problem down into smaller bits and solve each bit at a time.First, we need to translate the word problem into equation(s) with variables.Lever Problems deal with the lever principle described in word problems.Lever problem may involve 2 Objects or More than 2 Objects Mixture Problems involve items or quantities of different values that are mixed together.This may be for Two Persons, More Than Two Persons or Pipes Filling up a Tank For more Algebra Word Problems and Algebra techniques, go to our Have a look at the following videos for some introduction of how to solve algebra problems: Example: Angela sold eight more new cars this year than Carmen.If together they sold a total of 88 cars, how many cars did each of them sell?
