Whakaoti i te 7-11/4x+1/2x=10

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

Whakaoti mō x

$$x=-4$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 4, arā, te tauraro pātahi he tino iti rawa te kitea o 4,2.

$$4\left(7-\frac{1\times 4+1}{4}x\right)+2x=40$$

Whakareatia te 1 ki te 4, ka 4.

$$4\left(7-\frac{4+1}{4}x\right)+2x=40$$

Tāpirihia te 4 ki te 1, ka 5.

$$4\left(7-\frac{5}{4}x\right)+2x=40$$

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 7-\frac{5}{4}x.

$$28+4\left(-\frac{5}{4}\right)x+2x=40$$

Me whakakore te 4 me te 4.

$$28-5x+2x=40$$

Pahekotia te -5x me 2x, ka -3x.

$$28-3x=40$$

Tangohia te 28 mai i ngā taha e rua.

$$-3x=40-28$$

Tangohia te 28 i te 40, ka 12.

$$-3x=12$$

Whakawehea ngā taha e rua ki te -3.

$$x=\frac{12}{-3}$$

Whakawehea te 12 ki te -3, kia riro ko -4.

$$x=-4$$
