8-7x+7=0
Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te x-1.
15-7x=0
Tāpirihia te 8 ki te 7, ka 15.
-7x=-15
Tangohia te 15 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-15}{-7}
Whakawehea ngā taha e rua ki te -7.
x=\frac{15}{7}
Ka taea te hautanga \frac{-15}{-7} te whakamāmā ki te \frac{15}{7} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
