Issolvi -7/5x+21/5=-667/90

$$- \frac { 7 } { 5 } x + 2 \frac { 1 } { 5 } = - 6 \frac { 67 } { 90 }$$

Solvi għal x

$$x = \frac{115}{18} = 6\frac{7}{18} \approx 6.388888889$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika ż-żewġ naħat tal-ekwazzjoni b'90, l-inqas denominatur komuni ta' 5,90.

$$-126x+18\left(2\times 5+1\right)=-\left(6\times 90+67\right)$$

Immultiplika 2 u 5 biex tikseb 10.

$$-126x+18\left(10+1\right)=-\left(6\times 90+67\right)$$

Żid 10 u 1 biex tikseb 11.

$$-126x+18\times 11=-\left(6\times 90+67\right)$$

Immultiplika 18 u 11 biex tikseb 198.

$$-126x+198=-\left(6\times 90+67\right)$$

Immultiplika 6 u 90 biex tikseb 540.

$$-126x+198=-\left(540+67\right)$$

Żid 540 u 67 biex tikseb 607.

$$-126x+198=-607$$

Naqqas 198 miż-żewġ naħat.

$$-126x=-607-198$$

Naqqas 198 minn -607 biex tikseb -805.

$$-126x=-805$$

Iddividi ż-żewġ naħat b'-126.

$$x=\frac{-805}{-126}$$

Naqqas il-frazzjoni \frac{-805}{-126} għat-termini l-aktar baxxi billi testratta u tikkanċella barra -7.

$$x=\frac{115}{18}$$
