Issolvi 0.4*x+0.8/0.5=0.3x-0.4/0.4+1

$$\frac { 0.4 \times x + 0.8 } { 0.5 } = \frac { 0.3 x - 0.4 } { 0.4 } + 1$$

Solvi għal x

$$x=-32$$

Iddividi kull terminu ta' 0.4x+0.8 b'0.5 biex tikseb\frac{0.4x}{0.5}+\frac{0.8}{0.5}.

$$\frac{0.4x}{0.5}+\frac{0.8}{0.5}=\frac{0.3x-0.4}{0.4}+1$$

Iddividi 0.4x b'0.5 biex tikseb0.8x.

$$0.8x+\frac{0.8}{0.5}=\frac{0.3x-0.4}{0.4}+1$$

Espandi \frac{0.8}{0.5} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'10.

$$0.8x+\frac{8}{5}=\frac{0.3x-0.4}{0.4}+1$$

Iddividi kull terminu ta' 0.3x-0.4 b'0.4 biex tikseb\frac{0.3x}{0.4}+\frac{-0.4}{0.4}.

$$0.8x+\frac{8}{5}=\frac{0.3x}{0.4}+\frac{-0.4}{0.4}+1$$

Iddividi 0.3x b'0.4 biex tikseb0.75x.

$$0.8x+\frac{8}{5}=0.75x+\frac{-0.4}{0.4}+1$$

Iddividi -0.4 b'0.4 biex tikseb-1.

$$0.8x+\frac{8}{5}=0.75x-1+1$$

Żid -1 u 1 biex tikseb 0.

$$0.8x+\frac{8}{5}=0.75x$$

Naqqas 0.75x miż-żewġ naħat.

$$0.8x+\frac{8}{5}-0.75x=0$$

Ikkombina 0.8x u -0.75x biex tikseb 0.05x.

$$0.05x+\frac{8}{5}=0$$

Naqqas \frac{8}{5} miż-żewġ naħat. Xi ħaġa mnaqqsa minn żero tagħti numru negattiv.

$$0.05x=-\frac{8}{5}$$

Iddividi ż-żewġ naħat b'0.05.

$$x=\frac{-\frac{8}{5}}{0.05}$$

Esprimi \frac{-\frac{8}{5}}{0.05} bħala frazzjoni waħda.

$$x=\frac{-8}{5\times 0.05}$$

Immultiplika 5 u 0.05 biex tikseb 0.25.

$$x=\frac{-8}{0.25}$$

Espandi \frac{-8}{0.25} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'100.

$$x=\frac{-800}{25}$$

Iddividi -800 b'25 biex tikseb-32.

$$x=-32$$
