## Word problems that lead to simultaneous equations. Examples - A complete course in algebra

Word Problems on Simultaneous Equations :. Solving word problems on simultaneous equations is sometimes a difficult job for some students. Example 1 :. In a school, there are students in total. Let "x" and "y" be the no. Then, we have. Divide by 2. Hence, the number of boys in the school is and girls is Example 2 :. Lenin invests some amount in deposit A and some amount in deposit B. Let "x" and "y" be the amounts invested in A and B respectively.

Subtract y from both sides. Given : Mr. Multiply both sides by Example 3 :. The sum of two numbers is If one number is 7 less than two times of the other, then find the two numbers. Let "x" and "y" be the two numbers. Given : The sum of two numbers is Given : O ne number is 7 less than two times of the other. Add 7 to both sides. Divide both sides by 3. Example 4 :. The perimeter of the rectangle is cm. If the length is 7 more than 3 times the width, find the area of the rectangle.

Let "x" and "y" be the length and width of the rectangle respectively. Divide both sides by 2. Given **simultaneous equations problem solving** T he length is 7 more than 3 times the width.

So, we have. Therefore, the length of the rectangle is 61 cm and width is 18 cm. Example 5 :. A trader gains one third of the cost price as profit on a product and one fourth of the cost price as profit on other product.

Find *simultaneous equations problem solving* cost price of each product. Let "x" and "y" be the cost prices of the two products. Let the trader gain one third of the cost price as profit on the product whose cost price is x. Let the trader gain one fourth of the cost price as profit on the product whose cost price is y.
