Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika 5 u 6 biex tikseb 30.

$$212-5\left(a+3\left(30-17\right)\right)=12$$

Naqqas 17 minn 30 biex tikseb 13.

$$212-5\left(a+3\times 13\right)=12$$

Immultiplika 3 u 13 biex tikseb 39.

$$212-5\left(a+39\right)=12$$

Uża l-propjetà distributtiva biex timmultiplika -5 b'a+39.

$$212-5a-195=12$$

Naqqas 195 minn 212 biex tikseb 17.

$$17-5a=12$$

Naqqas 17 miż-żewġ naħat.

$$-5a=12-17$$

Naqqas 17 minn 12 biex tikseb -5.

$$-5a=-5$$

Iddividi ż-żewġ naħat b'-5.

$$a=\frac{-5}{-5}$$

Iddividi -5 b'-5 biex tikseb1.

$$a=1$$
