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 10 Bananas:

SOLVING A CLASSIC ALGEBRA EQUATION

HOW TO SOLVE A CLASSIC ALGEBRAIC EQUATION . Hello !   Sometime, in algebraic eqtiotions it is not always about solving for x or y. We have to solve for the whole equation, and today we are going to solve one equation of such kind of problem.       Supposed, we have been given an equation: Fourteen x minus three y divide by x plus four y is equal to 4 and ask to find the result of x minus two y. A classic algebraic equation. In this problem we can let the first given equation be equation one and the second given expression to be two, for the simplicity of the work. From that, we can simplify the first equation, by multiplying  each side by the denominator ( i.e x + y).  And then, collect the like term, so that all the terms with x will be on one and all the terms with y will be on the otherside of rhe equation. Therefore, we can let one of x or y to be the subject of the formula. So that, we will subtitute it in equation 2 given above. After we found th...

SOLVING A RADICAL EQUATION WITH UNLIKE ROOT. Hello everyone!          In this class we are going to learn how to solve a radical equation. Radical equation are the same, and today we are going to solve one them.    Normally, in solving a radical equation we are trying to take one of the radical term to other side and then isolate the other term. Typically we are going to take the cube root of both side, and that is going to be massive.               So, here we are going to apply another method which is going be a substitution method.            Now we have this equation in a single variable, for the time being Iam going to turn it in to more variables.           The first thing Iam going to do is that to replace the first radical with m and the second radical with n . So that the whole equation will change into  m + n = 1 Now from there i can get more equati...
