How do you Solve: -2x-7=-29

x=11

Step-by-step explanation: add 7 to both sides of the equal sign. the 7's get canceled out. -29 plus 7 is -22, bring down the -2x, so now you have -2x=-22, then you divide -2 on both sides (the -2x's get cancelled out)  and you get 11

hope I explained it good enough :)

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
