Whakaoti i te 2/3x+1/2=-3/8

$$\frac { 2 } { 3 } x + \frac { 1 } { 2 } = - 3 / 8$$

Whakaoti mō x

$$x = -\frac{21}{16} = -1\frac{5}{16} = -1.3125$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te \frac{1}{2} mai i ngā taha e rua.

$$\frac{2}{3}x=-\frac{3}{8}-\frac{1}{2}$$

Ko te maha noa iti rawa atu o 8 me 2 ko 8. Me tahuri -\frac{3}{8} me \frac{1}{2} ki te hautau me te tautūnga 8.

$$\frac{2}{3}x=-\frac{3}{8}-\frac{4}{8}$$

Tā te mea he rite te tauraro o -\frac{3}{8} me \frac{4}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{2}{3}x=\frac{-3-4}{8}$$

Tangohia te 4 i te -3, ka -7.

$$\frac{2}{3}x=-\frac{7}{8}$$

Me whakarea ngā taha e rua ki te \frac{3}{2}, te tau utu o \frac{2}{3}.

$$x=-\frac{7}{8}\times \frac{3}{2}$$

Me whakarea te -\frac{7}{8} ki te \frac{3}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x=\frac{-7\times 3}{8\times 2}$$

Mahia ngā whakarea i roto i te hautanga \frac{-7\times 3}{8\times 2}.

$$x=\frac{-21}{16}$$

Ka taea te hautanga \frac{-21}{16} te tuhi anō ko -\frac{21}{16} mā te tango i te tohu tōraro.

$$x=-\frac{21}{16}$$
