Whakaoti i te 34(x-1)-12(2x-2)=7(05)+2(2

$$34(x-1)-12(2x-2)=7(05)+2(2$$

Whakaoti mō x

$$x = \frac{49}{10} = 4\frac{9}{10} = 4.9$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 34 ki te x-1.

$$34x-34-12\left(2x-2\right)=7\times 5+2\times 2$$

Whakamahia te āhuatanga tohatoha hei whakarea te -12 ki te 2x-2.

$$34x-34-24x+24=7\times 5+2\times 2$$

Pahekotia te 34x me -24x, ka 10x.

$$10x-34+24=7\times 5+2\times 2$$

Tāpirihia te -34 ki te 24, ka -10.

$$10x-10=7\times 5+2\times 2$$

Whakareatia te 7 ki te 5, ka 35. Whakareatia te 2 ki te 2, ka 4.

$$10x-10=35+4$$

Tāpirihia te 35 ki te 4, ka 39.

$$10x-10=39$$

Me tāpiri te 10 ki ngā taha e rua.

$$10x=39+10$$

Tāpirihia te 39 ki te 10, ka 49.

$$10x=49$$

Whakawehea ngā taha e rua ki te 10.

$$x=\frac{49}{10}$$
