Kua tāruatia ki te papatopenga
x+5+2\times 2x=3\left(1-x\right)+6
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 6,3,2.
x+5+4x=3\left(1-x\right)+6
Whakareatia te 2 ki te 2, ka 4.
5x+5=3\left(1-x\right)+6
Pahekotia te x me 4x, ka 5x.
5x+5=3-3x+6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 1-x.
5x+5=9-3x
Tāpirihia te 3 ki te 6, ka 9.
5x+5+3x=9
Me tāpiri te 3x ki ngā taha e rua.
8x+5=9
Pahekotia te 5x me 3x, ka 8x.
8x=9-5
Tangohia te 5 mai i ngā taha e rua.
8x=4
Tangohia te 5 i te 9, ka 4.
x=\frac{4}{8}
Whakawehea ngā taha e rua ki te 8.
x=\frac{1}{2}
Whakahekea te hautanga \frac{4}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
