To solve 5(2x+4) =15 , first divide each side by

To solve 5(2x+4) =15

We need to remove 5 first

5 is multiplied with 2x+4

To remove 5 we do opposite operation

First divide each side by 5

2x + 4 = 3

Now subtract each side by 4

2x = -1

Now divide by 2 from both sides

so the value of x is

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
