-1-2(m+1)=2N+3

Solution for -1-2(m+1)=2N+3 equation:

Simplifying
-1 + -2(m + 1) = 2N + 3

Reorder the terms:
-1 + -2(1 + m) = 2N + 3
-1 + (1 * -2 + m * -2) = 2N + 3
-1 + (-2 + -2m) = 2N + 3

Combine like terms: -1 + -2 = -3
-3 + -2m = 2N + 3

Reorder the terms:
-3 + -2m = 3 + 2N

Solving
-3 + -2m = 3 + 2N

Solving for variable 'm'.

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

Add '3' to each side of the equation.
-3 + 3 + -2m = 3 + 3 + 2N

Combine like terms: -3 + 3 = 0
0 + -2m = 3 + 3 + 2N
-2m = 3 + 3 + 2N

Combine like terms: 3 + 3 = 6
-2m = 6 + 2N

Divide each side by '-2'.
m = -3 + -1N

Simplifying
m = -3 + -1N
