Whakaoti i te 3(x+5)/2-1/2(x+5)=2x+5/3

$$\frac { 3 ( x + 5 ) } { 2 } - \frac { 1 } { 2 } ( x + 5 ) = \frac { 2 x + 5 } { 3 }$$

Whakaoti mō x

$$x=-10$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3.

$$3\times 3\left(x+5\right)-3\left(x+5\right)=2\left(2x+5\right)$$

Whakareatia te 3 ki te 3, ka 9.

$$9\left(x+5\right)-3\left(x+5\right)=2\left(2x+5\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te x+5.

$$9x+45-3\left(x+5\right)=2\left(2x+5\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x+5.

$$9x+45-3x-15=2\left(2x+5\right)$$

Pahekotia te 9x me -3x, ka 6x.

$$6x+45-15=2\left(2x+5\right)$$

Tangohia te 15 i te 45, ka 30.

$$6x+30=2\left(2x+5\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x+5.

$$6x+30=4x+10$$

Tangohia te 4x mai i ngā taha e rua.

$$6x+30-4x=10$$

Pahekotia te 6x me -4x, ka 2x.

$$2x+30=10$$

Tangohia te 30 mai i ngā taha e rua.

$$2x=10-30$$

Tangohia te 30 i te 10, ka -20.

$$2x=-20$$

Whakawehea ngā taha e rua ki te 2.

$$x=\frac{-20}{2}$$

Whakawehea te -20 ki te 2, kia riro ko -10.

$$x=-10$$
