Kua tāruatia ki te papatopenga
2=5-5x+35
Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te x-7.
2=40-5x
Tāpirihia te 5 ki te 35, ka 40.
40-5x=2
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-5x=2-40
Tangohia te 40 mai i ngā taha e rua.
-5x=-38
Tangohia te 40 i te 2, ka -38.
x=\frac{-38}{-5}
Whakawehea ngā taha e rua ki te -5.
x=\frac{38}{5}
Ka taea te hautanga \frac{-38}{-5} te whakamāmā ki te \frac{38}{5} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
