Solve 4-6n=8(n+7) distributive propertiy

The distributive property tells you the product is found by multiplying each term inside parentheses by the factor outside.

... 4 -6n = 8n +8·7

... 4 = 14n +56 . . . . . . . add 6n to both sides

... -52 = 14n . . . . . . . . . subtract 56 from both sides

... -52/14 = -26/7 = n . . . divide by 14, reduce the fraction

The solution is ...

... n = -26/7 = -3 5/7

to rewrite a literal equation you may need to divide by a number, or by a variable.

hope i .

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
