6x+5-15x=12
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 1-3x.
-9x+5=12
Pahekotia te 6x me -15x, ka -9x.
-9x=12-5
Tangohia te 5 mai i ngā taha e rua.
-9x=7
Tangohia te 5 i te 12, ka 7.
x=\frac{7}{-9}
Whakawehea ngā taha e rua ki te -9.
x=-\frac{7}{9}
Ka taea te hautanga \frac{7}{-9} te tuhi anō ko -\frac{7}{9} mā te tango i te tohu tōraro.
