The way to look at this is:
number = opposite number less 38
Let X be Number, then -X is opposite number
The algebraic equation to solve then is:
X=-X-38
X%2BX=X-X-38
2X=-38
2x%2F2=-38%2F2
x=-19
You kind of need to do a sanity check with word problems. Is -19 38 less than its opposite? The opposite of -19 is 19. 19-38=-19. So the answer seems plausible.
The number is highlight%28-19%29
Happy Calculating!
