Kua tāruatia ki te papatopenga
3x+2\left(8x+10\right)-3\times 3x=36
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3.
3x+16x+20-3\times 3x=36
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 8x+10.
19x+20-3\times 3x=36
Pahekotia te 3x me 16x, ka 19x.
19x+20-9x=36
Whakareatia te -3 ki te 3, ka -9.
10x+20=36
Pahekotia te 19x me -9x, ka 10x.
10x=36-20
Tangohia te 20 mai i ngā taha e rua.
10x=16
Tangohia te 20 i te 36, ka 16.
x=\frac{16}{10}
Whakawehea ngā taha e rua ki te 10.
x=\frac{8}{5}
Whakahekea te hautanga \frac{16}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
