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

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

Whakaoti mō x

$$x = \frac{58}{5} = 11\frac{3}{5} = 11.6$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$10-4x+2=\frac{2}{5}-3x$$

Tāpirihia te 10 ki te 2, ka 12.

$$12-4x=\frac{2}{5}-3x$$

Me tāpiri te 3x ki ngā taha e rua.

$$12-4x+3x=\frac{2}{5}$$

Pahekotia te -4x me 3x, ka -x.

$$12-x=\frac{2}{5}$$

Tangohia te 12 mai i ngā taha e rua.

$$-x=\frac{2}{5}-12$$

Me tahuri te 12 ki te hautau \frac{60}{5}.

$$-x=\frac{2}{5}-\frac{60}{5}$$

Tā te mea he rite te tauraro o \frac{2}{5} me \frac{60}{5}, me tango rāua mā te tango i ō raua taurunga.

$$-x=\frac{2-60}{5}$$

Tangohia te 60 i te 2, ka -58.

$$-x=-\frac{58}{5}$$

Me whakarea ngā taha e rua ki te -1.

$$x=\frac{58}{5}$$
