Question

18=k+12 HELPPP WHATS K

Answer 1

Answer:

k=6

Step-by-step explanation:

18=k+12

you need to isolate k so you subtract 12 from both side

6=k

Answer 2

Hm ok, so the answer here would be k=6, and heres why:

So to solve these types of problems you must first separate the variables from the rest of the equation. Normally it is the Y variable if there is multiple variables like X and Y.

In this case, K is basically our Y. This is what the the first step for any problem like this:

$18=k+12\\\\-12+18=k+12-12$

The reason for this is to get the like types of variables, such as numbers and letters, on the same side.

NOW IF you come across a different question that has something like this:

$3k$

I'm using K and the same equation basically to keep things simple, but it's also true if there is a number next to a Y.... and sometimes X.

IF you see something like this, the next step to solve is this:

$6=3k\\\\\frac{6=3k}{3} \\2=k$

Anything after the first NOW IF is irrelevant to this question, but please keep it in mind just in case, ok? It may save you some work later.
