Tohaina
Kua tāruatia ki te papatopenga
x+4-\frac{3}{2}x=0
Tangohia te \frac{3}{2}x mai i ngā taha e rua.
-\frac{1}{2}x+4=0
Pahekotia te x me -\frac{3}{2}x, ka -\frac{1}{2}x.
-\frac{1}{2}x=-4
Tangohia te 4 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=-4\left(-2\right)
Me whakarea ngā taha e rua ki te -2, te tau utu o -\frac{1}{2}.
x=8
Whakareatia te -4 ki te -2, ka 8.
