Tohaina
Kua tāruatia ki te papatopenga
2-4x-24=5x-8
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te x+6.
-22-4x=5x-8
Tangohia te 24 i te 2, ka -22.
-22-4x-5x=-8
Tangohia te 5x mai i ngā taha e rua.
-22-9x=-8
Pahekotia te -4x me -5x, ka -9x.
-9x=-8+22
Me tāpiri te 22 ki ngā taha e rua.
-9x=14
Tāpirihia te -8 ki te 22, ka 14.
x=\frac{14}{-9}
Whakawehea ngā taha e rua ki te -9.
x=-\frac{14}{9}
Ka taea te hautanga \frac{14}{-9} te tuhi anō ko -\frac{14}{9} mā te tango i te tohu tōraro.
