648x-42x+1302=67
Whakamahia te āhuatanga tohatoha hei whakarea te -42 ki te x-31.
606x+1302=67
Pahekotia te 648x me -42x, ka 606x.
606x=67-1302
Tangohia te 1302 mai i ngā taha e rua.
606x=-1235
Tangohia te 1302 i te 67, ka -1235.
x=\frac{-1235}{606}
Whakawehea ngā taha e rua ki te 606.
x=-\frac{1235}{606}
Ka taea te hautanga \frac{-1235}{606} te tuhi anō ko -\frac{1235}{606} mā te tango i te tohu tōraro.
