Whakaoti i te X=7/8(Y+Z)

$$X = \frac { 7 } { 8 } ( Y + Z )$$

Whakaoti mō Y

$$Y=\frac{8X}{7}-Z$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te \frac{7}{8} ki te Y+Z.

$$X=\frac{7}{8}Y+\frac{7}{8}Z$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$\frac{7}{8}Y+\frac{7}{8}Z=X$$

Tangohia te \frac{7}{8}Z mai i ngā taha e rua.

$$\frac{7}{8}Y=X-\frac{7}{8}Z$$

He hanga arowhānui tō te whārite.

$$\frac{7}{8}Y=-\frac{7Z}{8}+X$$

Whakawehea ngā taha e rua o te whārite ki te \frac{7}{8}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{\frac{7}{8}Y}{\frac{7}{8}}=\frac{-\frac{7Z}{8}+X}{\frac{7}{8}}$$

Mā te whakawehe ki te \frac{7}{8} ka wetekia te whakareanga ki te \frac{7}{8}.

$$Y=\frac{-\frac{7Z}{8}+X}{\frac{7}{8}}$$

Whakawehe X-\frac{7Z}{8} ki te \frac{7}{8} mā te whakarea X-\frac{7Z}{8} ki te tau huripoki o \frac{7}{8}.

$$Y=\frac{8X}{7}-Z$$

Whakaoti mō X

$$X=\frac{7\left(Y+Z\right)}{8}$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te \frac{7}{8} ki te Y+Z.

$$X=\frac{7}{8}Y+\frac{7}{8}Z$$
