\frac{1}{2}x+2-\frac{1}{3}x=0
Tangohia te \frac{1}{3}x mai i ngā taha e rua.
\frac{1}{6}x+2=0
Pahekotia te \frac{1}{2}x me -\frac{1}{3}x, ka \frac{1}{6}x.
\frac{1}{6}x=-2
Tangohia te 2 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=-2\times 6
Me whakarea ngā taha e rua ki te 6, te tau utu o \frac{1}{6}.
x=-12
Whakareatia te -2 ki te 6, ka -12.
