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