-8x+42-15x=-17
Tangohia te 15x mai i ngā taha e rua.
-23x+42=-17
Pahekotia te -8x me -15x, ka -23x.
-23x=-17-42
Tangohia te 42 mai i ngā taha e rua.
-23x=-59
Tangohia te 42 i te -17, ka -59.
x=\frac{-59}{-23}
Whakawehea ngā taha e rua ki te -23.
x=\frac{59}{23}
Ka taea te hautanga \frac{-59}{-23} te whakamāmā ki te \frac{59}{23} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
