4\left(2x+15-10x-12\right)=5\left(x-1\right)+3\left(x+1\right)+18
Uża l-propjetà distributtiva biex timmultiplika 5 b'3-2x.
4\left(-8x+15-12\right)=5\left(x-1\right)+3\left(x+1\right)+18
Ikkombina 2x u -10x biex tikseb -8x.
4\left(-8x+3\right)=5\left(x-1\right)+3\left(x+1\right)+18
Naqqas 12 minn 15 biex tikseb 3.
-32x+12=5\left(x-1\right)+3\left(x+1\right)+18
Uża l-propjetà distributtiva biex timmultiplika 4 b'-8x+3.
-32x+12=5x-5+3\left(x+1\right)+18
Uża l-propjetà distributtiva biex timmultiplika 5 b'x-1.
-32x+12=5x-5+3x+3+18
Uża l-propjetà distributtiva biex timmultiplika 3 b'x+1.
-32x+12=8x-5+3+18
Ikkombina 5x u 3x biex tikseb 8x.
-32x+12=8x-2+18
Żid -5 u 3 biex tikseb -2.
-32x+12=8x+16
Żid -2 u 18 biex tikseb 16.
-32x+12-8x=16
Naqqas 8x miż-żewġ naħat.
-40x+12=16
Ikkombina -32x u -8x biex tikseb -40x.
-40x=16-12
Naqqas 12 miż-żewġ naħat.
-40x=4
Naqqas 12 minn 16 biex tikseb 4.
x=\frac{4}{-40}
Iddividi ż-żewġ naħat b'-40.
x=-\frac{1}{10}
Naqqas il-frazzjoni \frac{4}{-40} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 4.
