Whakaoti i te y-(4.9)=0.8[x-(1.5)]

$$y - ( 4.9 ) = 0.8 [ x - ( 1.5 ) ]$$

Whakaoti mō x

$$x=\frac{5y}{4}-4.625$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 0.8 ki te x-1.5.

$$y-4.9=0.8x-1.2$$

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

$$0.8x-1.2=y-4.9$$

Me tāpiri te 1.2 ki ngā taha e rua.

$$0.8x=y-4.9+1.2$$

Tāpirihia te -4.9 ki te 1.2, ka -3.7.

$$0.8x=y-3.7$$

Whakawehea ngā taha e rua o te whārite ki te 0.8, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{0.8x}{0.8}=\frac{y-3.7}{0.8}$$

Mā te whakawehe ki te 0.8 ka wetekia te whakareanga ki te 0.8.

$$x=\frac{y-3.7}{0.8}$$

Whakawehe y-3.7 ki te 0.8 mā te whakarea y-3.7 ki te tau huripoki o 0.8.

$$x=\frac{5y}{4}-\frac{37}{8}$$

Whakaoti mō y

$$y=\frac{4x}{5}+3.7$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te 0.8 ki te x-1.5.

$$y-4.9=0.8x-1.2$$

Me tāpiri te 4.9 ki ngā taha e rua.

$$y=0.8x-1.2+4.9$$

Tāpirihia te -1.2 ki te 4.9, ka 3.7.

$$y=0.8x+3.7$$
