Nx-a=nx+d

Solution for Nx-a=nx+d equation:

Simplifying
Nx + -1a = nx + d

Reorder the terms:
-1a + xN = nx + d

Reorder the terms:
-1a + xN = d + nx

Solving
-1a + xN = d + nx

Solving for variable 'a'.

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

Add '-1xN' to each side of the equation.
-1a + xN + -1xN = d + nx + -1xN

Combine like terms: xN + -1xN = 0
-1a + 0 = d + nx + -1xN
-1a = d + nx + -1xN

Divide each side by '-1'.
a = -1d + -1nx + xN

Simplifying
a = -1d + -1nx + xN
