Kua tāruatia ki te papatopenga
2x+6=3\left(-x\right)-18
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,2.
2x+6-3\left(-x\right)=-18
Tangohia te 3\left(-x\right) mai i ngā taha e rua.
2x+6-3\left(-1\right)x=-18
Whakareatia te -1 ki te 3, ka -3.
2x+6+3x=-18
Whakareatia te -3 ki te -1, ka 3.
5x+6=-18
Pahekotia te 2x me 3x, ka 5x.
5x=-18-6
Tangohia te 6 mai i ngā taha e rua.
5x=-24
Tangohia te 6 i te -18, ka -24.
x=\frac{-24}{5}
Whakawehea ngā taha e rua ki te 5.
x=-\frac{24}{5}
Ka taea te hautanga \frac{-24}{5} te tuhi anō ko -\frac{24}{5} mā te tango i te tohu tōraro.
