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

Word Problems on Simultaneous Equations - Examples. Example 1: In a school, there are students in total. If there is 20% more boys than girls, find the number of boys and girls in the school. Solve a Simultaneous Set of Two Linear Equations. This page will show you how to solve two equations with two unknowns. There are many ways of doing this, but this page used the method of substitution. Note the "=" signs are already put in for you. You just need to fill in the boxes "around" the equals signs. Solving the solution of two variables of system equation that leads for the word problems on simultaneous linear equations is the ordered pair (x, y) which satisfies both the linear equations.

Word Problems on Simultaneous Equations :. Solving word problems on simultaneous equations is sometimes a difficult job for some students, simultaneous equations problem solving. Example 1 :. In a school, there are students in total. Let "x" and "y" be the no. Then, simultaneous equations problem solving, 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 : 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 the cost price of simultaneous equations problem solving 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.
