rad(x+27)-rad(x-13)=3

Solution for rad(x+27)-rad(x-13)=3 equation:

Simplifying
rad(x + 27) + -1rad(x + -13) = 3

Reorder the terms:
adr(27 + x) + -1rad(x + -13) = 3
(27 * adr + x * adr) + -1rad(x + -13) = 3
(27adr + adrx) + -1rad(x + -13) = 3

Reorder the terms:
27adr + adrx + -1adr(-13 + x) = 3
27adr + adrx + (-13 * -1adr + x * -1adr) = 3
27adr + adrx + (13adr + -1adrx) = 3

Reorder the terms:
27adr + 13adr + adrx + -1adrx = 3

Combine like terms: 27adr + 13adr = 40adr
40adr + adrx + -1adrx = 3

Combine like terms: adrx + -1adrx = 0
40adr + 0 = 3
40adr = 3
