Question

How do you solve a linear equation

Answer 1

It is hard to explain without a picture. You have the line graph and depending on what your numbers are, you place them where the teacher, (or paper) says too. You would then move two to the right, and one up. You would keep repeating that pattern until you got to the top of the graph. After that you would draw a strait line through it. If you are dealing with negative numbers, then depending on which one is negative, you would move two to the LEFT from the starting point and go one up. You repeat that pattern as well, then once you reach the top of the page you draw a line through it.

Step-by-step explanation:

To solve a linear equation

1) we need to identify the first and second equation

ex: 2x + 3y = 18  ( first equation )

      x  +  y  = 6     ( second equation )

2) After identifying, we need to form a third equation from any one of the given equations and find the value of either one of the variables.

ex :  x + y = 6

       x = 6 - y    ( third equation )

3) With the third equation formed , we can find the value of the other variable by applying the third equation in the first equation.

ex:  2x + 3y = 18

    2 ( 6 - y ) + 3y = 18

   12 - 2y + 3y = 18

   12 + y = 18

    y = 18 - 12

    y = 6

4) Having found the value of one variable, we can find the value of the other by applying the value of the found variable in the first, second or third equations.

ex : x + y = 6

     x + (6) = 6  ( found value of "Y" is 6 )

    x  =  6 - 6

  x  = 0

5) With this, we have found the values of the 2 variables and hence solved the question.

ex:   x = 0

       y = 6
