Issolvi 0.4y+0.9/5-0.3+0.2y/0.3=1

$$\frac { 0.4 y + 0.9 } { 5 } - \frac { 0.3 + 0.2 y } { 0.3 } = 1$$

Solvi għal y

$$y = -\frac{273}{88} = -3\frac{9}{88} \approx -3.102272727$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika ż-żewġ naħat tal-ekwazzjoni b'5.

$$0.4y+0.9-5\times \frac{0.3+0.2y}{0.3}=5$$

Iddividi kull terminu ta' 0.3+0.2y b'0.3 biex tikseb\frac{0.3}{0.3}+\frac{0.2y}{0.3}.

$$0.4y+0.9-5\left(\frac{0.3}{0.3}+\frac{0.2y}{0.3}\right)=5$$

Iddividi 0.3 b'0.3 biex tikseb1.

$$0.4y+0.9-5\left(1+\frac{0.2y}{0.3}\right)=5$$

Iddividi 0.2y b'0.3 biex tikseb\frac{2}{3}y.

$$0.4y+0.9-5\left(1+\frac{2}{3}y\right)=5$$

Uża l-propjetà distributtiva biex timmultiplika -5 b'1+\frac{2}{3}y.

$$0.4y+0.9-5-\frac{10}{3}y=5$$

Naqqas 5 minn 0.9 biex tikseb -4.1.

$$0.4y-4.1-\frac{10}{3}y=5$$

Ikkombina 0.4y u -\frac{10}{3}y biex tikseb -\frac{44}{15}y.

$$-\frac{44}{15}y-4.1=5$$

Żid 4.1 maż-żewġ naħat.

$$-\frac{44}{15}y=5+4.1$$

Żid 5 u 4.1 biex tikseb 9.1.

$$-\frac{44}{15}y=9.1$$

Iddividi ż-żewġ naħat b'-\frac{44}{15}.

$$y=\frac{9.1}{-\frac{44}{15}}$$
