Kua tāruatia ki te papatopenga
15x+x-25=1+25x
Whakareatia ngā taha e rua o te whārite ki te 5.
16x-25=1+25x
Pahekotia te 15x me x, ka 16x.
16x-25-25x=1
Tangohia te 25x mai i ngā taha e rua.
-9x-25=1
Pahekotia te 16x me -25x, ka -9x.
-9x=1+25
Me tāpiri te 25 ki ngā taha e rua.
-9x=26
Tāpirihia te 1 ki te 25, ka 26.
x=\frac{26}{-9}
Whakawehea ngā taha e rua ki te -9.
x=-\frac{26}{9}
Ka taea te hautanga \frac{26}{-9} te tuhi anō ko -\frac{26}{9} mā te tango i te tohu tōraro.
