-(r+n+t)=

Solution for -(r+n+t)= equation:

Simplifying
-1(r + n + t) = 0

Reorder the terms:
-1(n + r + t) = 0
(n * -1 + r * -1 + t * -1) = 0
(-1n + -1r + -1t) = 0

Solving
-1n + -1r + -1t = 0

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add 'r' to each side of the equation.
-1n + -1r + r + -1t = 0 + r

Combine like terms: -1r + r = 0
-1n + 0 + -1t = 0 + r
-1n + -1t = 0 + r
Remove the zero:
-1n + -1t = r

Add 't' to each side of the equation.
-1n + -1t + t = r + t

Combine like terms: -1t + t = 0
-1n + 0 = r + t
-1n = r + t

Divide each side by '-1'.
n = -1r + -1t

Simplifying
n = -1r + -1t
