Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika ż-żewġ naħat tal-ekwazzjoni b'12, l-inqas denominatur komuni ta' 2,3,4.

$$6\times \frac{3\times 2+1}{2}-4\left(2\times 3+1\right)y=3\left(3\times 4+1\right)$$

Immultiplika 3 u 2 biex tikseb 6.

$$6\times \frac{6+1}{2}-4\left(2\times 3+1\right)y=3\left(3\times 4+1\right)$$

Żid 6 u 1 biex tikseb 7.

$$6\times \frac{7}{2}-4\left(2\times 3+1\right)y=3\left(3\times 4+1\right)$$

Esprimi 6\times \frac{7}{2} bħala frazzjoni waħda.

$$\frac{6\times 7}{2}-4\left(2\times 3+1\right)y=3\left(3\times 4+1\right)$$

Immultiplika 6 u 7 biex tikseb 42.

$$\frac{42}{2}-4\left(2\times 3+1\right)y=3\left(3\times 4+1\right)$$

Iddividi 42 b'2 biex tikseb21.

$$21-4\left(2\times 3+1\right)y=3\left(3\times 4+1\right)$$

Immultiplika 2 u 3 biex tikseb 6.

$$21-4\left(6+1\right)y=3\left(3\times 4+1\right)$$

Żid 6 u 1 biex tikseb 7.

$$21-4\times 7y=3\left(3\times 4+1\right)$$

Immultiplika 4 u 7 biex tikseb 28.

$$21-28y=3\left(3\times 4+1\right)$$

Immultiplika 3 u 4 biex tikseb 12.

$$21-28y=3\left(12+1\right)$$

Żid 12 u 1 biex tikseb 13.

$$21-28y=3\times 13$$

Immultiplika 3 u 13 biex tikseb 39.

$$21-28y=39$$

Naqqas 21 miż-żewġ naħat.

$$-28y=39-21$$

Naqqas 21 minn 39 biex tikseb 18.

$$-28y=18$$

Iddividi ż-żewġ naħat b'-28.

$$y=\frac{18}{-28}$$

Naqqas il-frazzjoni \frac{18}{-28} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 2.

$$y=-\frac{9}{14}$$
