Passi tas-Soluzzjonijiet

Immultiplika -3 u 7 biex tikseb -21.

$$\left(-x^{2}\right)y-\left(-21x^{2}y\right)+\frac{16x^{2}y^{3}z}{4y^{2}z}$$

L-oppost ta' -21x^{2}y huwa 21x^{2}y.

$$\left(-x^{2}\right)y+21x^{2}y+\frac{16x^{2}y^{3}z}{4y^{2}z}$$

Annulla 4zy^{2} fin-numeratur u d-denominatur.

$$\left(-x^{2}\right)y+21x^{2}y+4yx^{2}$$

Ikkombina 21x^{2}y u 4yx^{2} biex tikseb 25x^{2}y.

$$\left(-x^{2}\right)y+25x^{2}y$$

Ikkombina -x^{2}y u 25x^{2}y biex tikseb 24x^{2}y.

$$24x^{2}y$$
