Whakaoti i te 02x+4/5y-(-2/5x)+1/10y+7/5y-2y

$$02 x + \frac { 4 } { 5 } y - ( - \frac { 2 } { 5 } x ) + \frac { 1 } { 10 } y + \frac { 7 } { 5 } y - 2 y$$

Aromātai

$$\frac{2x}{5}+\frac{3y}{10}$$

Ngā Upane Otinga

Whakareatia te 0 ki te 2, ka 0.

$$0x+\frac{4}{5}y-\left(-\frac{2}{5}x\right)+\frac{1}{10}y+\frac{7}{5}y-2y$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$0+\frac{4}{5}y-\left(-\frac{2}{5}x\right)+\frac{1}{10}y+\frac{7}{5}y-2y$$

Ko te tau i tāpiria he kore ka hua koia tonu.

$$\frac{4}{5}y-\left(-\frac{2}{5}x\right)+\frac{1}{10}y+\frac{7}{5}y-2y$$

Ko te tauaro o -\frac{2}{5}x ko \frac{2}{5}x.

$$\frac{4}{5}y+\frac{2}{5}x+\frac{1}{10}y+\frac{7}{5}y-2y$$

Pahekotia te \frac{4}{5}y me \frac{1}{10}y, ka \frac{9}{10}y.

$$\frac{9}{10}y+\frac{2}{5}x+\frac{7}{5}y-2y$$

Pahekotia te \frac{9}{10}y me \frac{7}{5}y, ka \frac{23}{10}y.

$$\frac{23}{10}y+\frac{2}{5}x-2y$$

Pahekotia te \frac{23}{10}y me -2y, ka \frac{3}{10}y.

$$\frac{3}{10}y+\frac{2}{5}x$$

Tauwehe

$$\frac{4x+3y}{10}$$

Ngā Upane Otinga

Tauwehea te \frac{1}{10}.

$$\frac{0+8y+4x+y+14y-20y}{10}$$

Whakaarohia te 8y+4x+y+14y-20y. Whakarea ka paheko i ngā kīanga tau ōrite.

$$4x+3y$$

Me tuhi anō te kīanga whakatauwehe katoa.

$$\frac{4x+3y}{10}$$
