The sum of 7 and the product of a number x and 12

-7/12

Step-by-step explanation:

An equation can be made out of this problem.

Sum means adding, so in this problem, you are adding 7 to the product of x and 12.

Product means multiplying, so you are multiplying x by twelve to get 12x.

Since you are adding all of this to 7, you get the equation 7 + 12x = 0.

Now, you just need to solve for x by subtracting the 7 over, giving you 12x = -7.

Now, to isolate x, divide both sides by 12. The twelves on the left cancel each other out, leaving you with -7/12.

no this is a nonlinear negative
