Koraci rješenja

Pomnožite 0 i 0 da biste dobili 0.

$$0\times 1\left(x+18\right)-0\times 18=0\times 0\times 1\left(7x+18\right)$$

Pomnožite 0 i 1 da biste dobili 0.

$$0\left(x+18\right)-0\times 18=0\times 0\times 1\left(7x+18\right)$$

Sve puta nula daje nulu.

$$0-0\times 18=0\times 0\times 1\left(7x+18\right)$$

Pomnožite 0 i 18 da biste dobili 0.
