Issolvi 0.14(R+15)=0.2(R+9)

$$0.14 ( R + 15 ) = 0.2 ( R + 9 )$$

Solvi għal R

$$R=5$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika 0.14 b'R+15.

$$0.14R+2.1=0.2\left(R+9\right)$$

Uża l-propjetà distributtiva biex timmultiplika 0.2 b'R+9.

$$0.14R+2.1=0.2R+1.8$$

Naqqas 0.2R miż-żewġ naħat.

$$0.14R+2.1-0.2R=1.8$$

Ikkombina 0.14R u -0.2R biex tikseb -0.06R.

$$-0.06R+2.1=1.8$$

Naqqas 2.1 miż-żewġ naħat.

$$-0.06R=1.8-2.1$$

Naqqas 2.1 minn 1.8 biex tikseb -0.3.

$$-0.06R=-0.3$$

Iddividi ż-żewġ naħat b'-0.06.

$$R=\frac{-0.3}{-0.06}$$

Espandi \frac{-0.3}{-0.06} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'100.

$$R=\frac{-30}{-6}$$

Iddividi -30 b'-6 biex tikseb5.

$$R=5$$
