2\times 5x-12=-\left(5x-2\right)+3\left(3x+2\right)
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,6,2.
10x-12=-\left(5x-2\right)+3\left(3x+2\right)
Whakareatia te 2 ki te 5, ka 10.
10x-12=-5x-\left(-2\right)+3\left(3x+2\right)
Hei kimi i te tauaro o 5x-2, kimihia te tauaro o ia taurangi.
10x-12=-5x+2+3\left(3x+2\right)
Ko te tauaro o -2 ko 2.
10x-12=-5x+2+9x+6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 3x+2.
10x-12=4x+2+6
Pahekotia te -5x me 9x, ka 4x.
10x-12=4x+8
Tāpirihia te 2 ki te 6, ka 8.
10x-12-4x=8
Tangohia te 4x mai i ngā taha e rua.
6x-12=8
Pahekotia te 10x me -4x, ka 6x.
6x=8+12
Me tāpiri te 12 ki ngā taha e rua.
6x=20
Tāpirihia te 8 ki te 12, ka 20.
x=\frac{20}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{10}{3}
Whakahekea te hautanga \frac{20}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
