Whakamahia te āhuatanga tohatoha hei whakarea te \frac{1}{2}+x ki te 100.

$$\frac{1}{2}\times 100+100x=150x$$

Whakareatia te \frac{1}{2} ki te 100, ka \frac{100}{2}.

$$\frac{100}{2}+100x=150x$$

Whakawehea te 100 ki te 2, kia riro ko 50.

$$50+100x=150x$$

Tangohia te 150x mai i ngā taha e rua.

$$50+100x-150x=0$$

Pahekotia te 100x me -150x, ka -50x.

$$50-50x=0$$

Tangohia te 50 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$-50x=-50$$

Whakawehea ngā taha e rua ki te -50.

$$x=\frac{-50}{-50}$$

Whakawehea te -50 ki te -50, kia riro ko 1.

$$x=1$$
