Lineāra vienādojuma risināšanas darbības

Reiziniet abas vienādojuma puses ar 6x\left(x+1\right), kas ir mazākais x+1,x,6 skaitlis, kurš dalās bez atlikuma.

$$6xgyx+\left(6x+6\right)\left(x+1\right)=13x\left(x+1\right)$$

Reiziniet x un x, lai iegūtu x^{2}.

$$6x^{2}gy+\left(6x+6\right)\left(x+1\right)=13x\left(x+1\right)$$

Izmantojiet distributīvo īpašību, lai reizinātu 6x+6 ar x+1 un apvienotu līdzīgos locekļus.

$$6x^{2}gy+6x^{2}+12x+6=13x\left(x+1\right)$$

Izmantojiet distributīvo īpašību, lai reizinātu 13x ar x+1.

$$6x^{2}gy+6x^{2}+12x+6=13x^{2}+13x$$

Atņemiet 6x^{2} no abām pusēm.

$$6x^{2}gy+12x+6=13x^{2}+13x-6x^{2}$$

Savelciet 13x^{2} un -6x^{2}, lai iegūtu 7x^{2}.

$$6x^{2}gy+12x+6=7x^{2}+13x$$

Atņemiet 12x no abām pusēm.

$$6x^{2}gy+6=7x^{2}+13x-12x$$

Savelciet 13x un -12x, lai iegūtu x.

$$6x^{2}gy+6=7x^{2}+x$$

Atņemiet 6 no abām pusēm.

$$6x^{2}gy=7x^{2}+x-6$$

Vienādojums ir standarta formā.

$$6yx^{2}g=7x^{2}+x-6$$

Daliet abas puses ar 6x^{2}y.

$$\frac{6yx^{2}g}{6yx^{2}}=\frac{\left(7x-6\right)\left(x+1\right)}{6yx^{2}}$$

Dalīšana ar 6x^{2}y atsauc reizināšanu ar 6x^{2}y.

$$g=\frac{\left(7x-6\right)\left(x+1\right)}{6yx^{2}}$$
