Kua tāruatia ki te papatopenga
9+6x+3=1-2x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x+1.
12+6x=1-2x
Tāpirihia te 9 ki te 3, ka 12.
12+6x+2x=1
Me tāpiri te 2x ki ngā taha e rua.
12+8x=1
Pahekotia te 6x me 2x, ka 8x.
8x=1-12
Tangohia te 12 mai i ngā taha e rua.
8x=-11
Tangohia te 12 i te 1, ka -11.
x=\frac{-11}{8}
Whakawehea ngā taha e rua ki te 8.
x=-\frac{11}{8}
Ka taea te hautanga \frac{-11}{8} te tuhi anō ko -\frac{11}{8} mā te tango i te tohu tōraro.
