SOLVING A WORD PROBLEM USING SEMULTINEOUS LINEAR EQUATION.
There are so many ways of solving a word problems, depending on the types of the problems given. One of such ways is by using semulteneous equation. Today we are going to solve a linear problem involving semulteneous e EXAMPLE: To solve such kind of question. Firstly we need to convert the statement into an equations. Now we can generate an equations using the above given information as below : So, let us use equation 1 and 2 semultineously to find the value of x and y. Using an elimination method we can still create another two equations from equation one and two above: By doing so we have obtained another two equations as below: By solving equation three and four above semultineously we will have: Then the value of x will be: Now, to find the value of y, we have to substitute the above value of x in to anyone of the above four equations. Since we have the values of x and y, this means that: Hence: Now we can easily find the cost of 7 apples and 1...
