PLS HELP 3x = 10 = 13x?

3x=10+13x

We simplify the equation to the form, which is simple to understand  

3x=10+13x

We move all terms containing x to the left and all other terms to the right.  

+3x-13x=+10

We simplify left and right side of the equation.  

-10x=+10

We divide both sides of the equation by -10 to get x.  

x=-1                     

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
