Issolvi 5*20+(x-5)*4=(5*20+44)*09

$$5 \times 20 + ( x - 5 ) \times 4 = ( 5 \times 20 + 44 ) \times 09$$

Solvi għal x

$$x=-20$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika 5 u 20 biex tikseb 100.

$$100+\left(x-5\right)\times 4=\left(5\times 20+44\right)\times 0\times 9$$

Uża l-propjetà distributtiva biex timmultiplika x-5 b'4.

$$100+4x-20=\left(5\times 20+44\right)\times 0\times 9$$

Naqqas 20 minn 100 biex tikseb 80.

$$80+4x=\left(5\times 20+44\right)\times 0\times 9$$

Immultiplika 5 u 20 biex tikseb 100.

$$80+4x=\left(100+44\right)\times 0\times 9$$

Żid 100 u 44 biex tikseb 144.

$$80+4x=144\times 0\times 9$$

Immultiplika 144 u 0 biex tikseb 0.

$$80+4x=0\times 9$$

Immultiplika 0 u 9 biex tikseb 0.

$$80+4x=0$$

Naqqas 80 miż-żewġ naħat. Xi ħaġa mnaqqsa minn żero tagħti numru negattiv.

$$4x=-80$$

Iddividi ż-żewġ naħat b'4.

$$x=\frac{-80}{4}$$

Iddividi -80 b'4 biex tikseb-20.

$$x=-20$$
