mod(x+3)+mod(x-3)=7

Solution for mod(x+3)+mod(x-3)=7 equation:

Simplifying
mod(x + 3) + mod(x + -3) = 7

Reorder the terms:
dmo(3 + x) + mod(x + -3) = 7
(3 * dmo + x * dmo) + mod(x + -3) = 7
(3dmo + dmox) + mod(x + -3) = 7

Reorder the terms:
3dmo + dmox + dmo(-3 + x) = 7
3dmo + dmox + (-3 * dmo + x * dmo) = 7
3dmo + dmox + (-3dmo + dmox) = 7

Reorder the terms:
3dmo + -3dmo + dmox + dmox = 7

Combine like terms: 3dmo + -3dmo = 0
0 + dmox + dmox = 7
dmox + dmox = 7

Combine like terms: dmox + dmox = 2dmox
2dmox = 7

Solving
2dmox = 7

Solving for variable 'd'.

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

Divide each side by '2mox'.
d = 3.5m-1o-1x-1

Simplifying
d = 3.5m-1o-1x-1
