Question

find -x when x=77 please explain how I figure this out

Answer 1

-x means the opposite of x. So if x is 77, then the opposite of x is -77.

Answer 2

Or you could write this equation: x = 77 Now multiply both sides by negative 1
-1(x) = -1(77)
-x = -77

Answer 3

-x is -1 ttimes x. meaning
-1x=77
and if i divide -1 on both sides then x=-77
