Solution for n=a+(n-31)d equation:


Simplifying
n = a + (n + -31) * d

Reorder the terms:
n = a + (-31 + n) * d

Reorder the terms for easier multiplication:
n = a + d(-31 + n)
n = a + (-31 * d + n * d)
n = a + (-31d + dn)

Solving
n = a + -31d + dn

Solving for variable 'n'.

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

Add '-1dn' to each side of the equation.
-1dn + n = a + -31d + dn + -1dn

Combine like terms: dn + -1dn = 0
-1dn + n = a + -31d + 0
-1dn + n = a + -31d

Reorder the terms:
-1a + 31d + -1dn + n = a + -31d + -1a + 31d

Reorder the terms:
-1a + 31d + -1dn + n = a + -1a + -31d + 31d

Combine like terms: a + -1a = 0
-1a + 31d + -1dn + n = 0 + -31d + 31d
-1a + 31d + -1dn + n = -31d + 31d

Combine like terms: -31d + 31d = 0
-1a + 31d + -1dn + n = 0
