Kua tāruatia ki te papatopenga
6x+15=6-x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x+5.
6x+15+x=6
Me tāpiri te x ki ngā taha e rua.
7x+15=6
Pahekotia te 6x me x, ka 7x.
7x=6-15
Tangohia te 15 mai i ngā taha e rua.
7x=-9
Tangohia te 15 i te 6, ka -9.
x=\frac{-9}{7}
Whakawehea ngā taha e rua ki te 7.
x=-\frac{9}{7}
Ka taea te hautanga \frac{-9}{7} te tuhi anō ko -\frac{9}{7} mā te tango i te tohu tōraro.
