Issolvi 15*500*(150-x)=2*4200left(x-25right)

$$15 \cdot 500 \cdot (150-x) = 2 \cdot 4200 \left( x-25 \right)$$

Solvi għal x

$$x = \frac{4450}{53} = 83\frac{51}{53} \approx 83.962264151$$

Immultiplika 15 u 500 biex tikseb 7500.

$$7500\left(150-x\right)=2\times 4200\left(x-25\right)$$

Uża l-propjetà distributtiva biex timmultiplika 7500 b'150-x.

$$1125000-7500x=2\times 4200\left(x-25\right)$$

Immultiplika 2 u 4200 biex tikseb 8400.

$$1125000-7500x=8400\left(x-25\right)$$

Uża l-propjetà distributtiva biex timmultiplika 8400 b'x-25.

$$1125000-7500x=8400x-210000$$

Naqqas 8400x miż-żewġ naħat.

$$1125000-7500x-8400x=-210000$$

Ikkombina -7500x u -8400x biex tikseb -15900x.

$$1125000-15900x=-210000$$

Naqqas 1125000 miż-żewġ naħat.

$$-15900x=-210000-1125000$$

Naqqas 1125000 minn -210000 biex tikseb -1335000.

$$-15900x=-1335000$$

Iddividi ż-żewġ naħat b'-15900.

$$x=\frac{-1335000}{-15900}$$

Naqqas il-frazzjoni \frac{-1335000}{-15900} għat-termini l-aktar baxxi billi testratta u tikkanċella barra -300.

$$x=\frac{4450}{53}$$
