Whakaoti i te 1/4+7/12x=1

$$\frac { 1 } { 4 } + \frac { 7 } { 12 } x = 1$$

Whakaoti mō x

$$x = \frac{9}{7} = 1\frac{2}{7} \approx 1.285714286$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te \frac{1}{4} mai i ngā taha e rua.

$$\frac{7}{12}x=1-\frac{1}{4}$$

Me tahuri te 1 ki te hautau \frac{4}{4}.

$$\frac{7}{12}x=\frac{4}{4}-\frac{1}{4}$$

Tā te mea he rite te tauraro o \frac{4}{4} me \frac{1}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{7}{12}x=\frac{4-1}{4}$$

Tangohia te 1 i te 4, ka 3.

$$\frac{7}{12}x=\frac{3}{4}$$

Me whakarea ngā taha e rua ki te \frac{12}{7}, te tau utu o \frac{7}{12}.

$$x=\frac{3}{4}\times \frac{12}{7}$$

Me whakarea te \frac{3}{4} ki te \frac{12}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x=\frac{3\times 12}{4\times 7}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 12}{4\times 7}.

$$x=\frac{36}{28}$$

Whakahekea te hautanga \frac{36}{28} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$x=\frac{9}{7}$$
