Whakaoti i te 11*(x-2)=-3*(x-7)+3*(5x+9)

$$11 \cdot ( x - 2 ) = - 3 \cdot ( x - 7 ) + 3 \cdot ( 5 x + 9 )$$

Whakaoti mō x

$$x=-70$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 11 ki te x-2.

$$11x-22=-3\left(x-7\right)+3\left(5x+9\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x-7.

$$11x-22=-3x+21+3\left(5x+9\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 5x+9.

$$11x-22=-3x+21+15x+27$$

Pahekotia te -3x me 15x, ka 12x.

$$11x-22=12x+21+27$$

Tāpirihia te 21 ki te 27, ka 48.

$$11x-22=12x+48$$

Tangohia te 12x mai i ngā taha e rua.

$$11x-22-12x=48$$

Pahekotia te 11x me -12x, ka -x.

$$-x-22=48$$

Me tāpiri te 22 ki ngā taha e rua.

$$-x=48+22$$

Tāpirihia te 48 ki te 22, ka 70.

$$-x=70$$

Me whakarea ngā taha e rua ki te -1.

$$x=-70$$
