7-6x+6=7x-\left(1-6x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -6 ki te x-1.
13-6x=7x-\left(1-6x\right)
Tāpirihia te 7 ki te 6, ka 13.
13-6x=7x-1-\left(-6x\right)
Hei kimi i te tauaro o 1-6x, kimihia te tauaro o ia taurangi.
13-6x=7x-1+6x
Ko te tauaro o -6x ko 6x.
13-6x=13x-1
Pahekotia te 7x me 6x, ka 13x.
13-6x-13x=-1
Tangohia te 13x mai i ngā taha e rua.
13-19x=-1
Pahekotia te -6x me -13x, ka -19x.
-19x=-1-13
Tangohia te 13 mai i ngā taha e rua.
-19x=-14
Tangohia te 13 i te -1, ka -14.
x=\frac{-14}{-19}
Whakawehea ngā taha e rua ki te -19.
x=\frac{14}{19}
Ka taea te hautanga \frac{-14}{-19} te whakamāmā ki te \frac{14}{19} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
