Whakaoti i te 35(2x-1)=7(x+4)+3x

$$35 ( 2 x - 1 ) = 7 ( x + 4 ) + 3 x$$

Whakaoti mō x

$$x = \frac{21}{20} = 1\frac{1}{20} = 1.05$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 35 ki te 2x-1.

$$70x-35=7\left(x+4\right)+3x$$

Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te x+4.

$$70x-35=7x+28+3x$$

Pahekotia te 7x me 3x, ka 10x.

$$70x-35=10x+28$$

Tangohia te 10x mai i ngā taha e rua.

$$70x-35-10x=28$$

Pahekotia te 70x me -10x, ka 60x.

$$60x-35=28$$

Me tāpiri te 35 ki ngā taha e rua.

$$60x=28+35$$

Tāpirihia te 28 ki te 35, ka 63.

$$60x=63$$

Whakawehea ngā taha e rua ki te 60.

$$x=\frac{63}{60}$$

Whakahekea te hautanga \frac{63}{60} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$x=\frac{21}{20}$$
