We are solving for x
first off we add 4 to -18 giving us -14
(If you are confused of how I got this there will be an explanation below*)
now we have -14+X=19
X will be whatever makes that -14 into 19
So we know we can knock out that -14 by adding 14 so far this makes X=14
making the total on that side 0
but 0 does not equal 19
now all we have to do is add 19 to X (which is 14) to get our final answer:
33
so X=33
lets plug this in
-14+33=19
if we add a negative number to a positive number it's the same as just subtracting
so 33-14=19
Now that we know our answer is correct we can Use that big ol #2 pencil and add that answer in and do the rest!
May the odds be ever in your favor
also if you were wondering about the -18+4=-14 here is the explanation
If I borrowed 18 bucks from Benedict cumberbatch I would be -18 dollars in debt
if I payed him 4 dollars I would only be 14 dollars in debt
get it?
