Math Help

My little brother needs help in 8th grade algebra, and it's been a while for me...

Here is the question:
Find a number that is 38 less than it's opposite.

Would that be x= -|x|-38

Thanks!

It worries me that I'm in my 2nd year of a maths degree and can't do this question...

No solution..that always the answer when I don't know!

umm!


x= -|x|-38


the | | means find the absolute value, and x is in the center so fin the absolute value of x but since it has a negitive sighn out of the absolute value symbol.

Maybe that would help him! Good luck!


Almost have the answere!

I think it's just:

-x - 38 = x

so, x = -19

Which makes sense. -19 is 38 less than its opposite, +19.

The answer is -19

Edit: AAH...you got there first

ANSWERE!!!!!!!



x=-19


And im only in 7th grade

Yep.

x=-x-38

Which would be x=-19.

Like everyone else has said.
