Kua tāruatia ki te papatopenga
2x-14=3x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-7.
2x-14-3x=0
Tangohia te 3x mai i ngā taha e rua.
-x-14=0
Pahekotia te 2x me -3x, ka -x.
-x=14
Me tāpiri te 14 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=-14
Me whakarea ngā taha e rua ki te -1.
