Kua tāruatia ki te papatopenga
-\frac{3}{4}x=-1-5
Tangohia te 5 mai i ngā taha e rua.
-\frac{3}{4}x=-6
Tangohia te 5 i te -1, ka -6.
x=-6\left(-\frac{4}{3}\right)
Me whakarea ngā taha e rua ki te -\frac{4}{3}, te tau utu o -\frac{3}{4}.
x=\frac{-6\left(-4\right)}{3}
Tuhia te -6\left(-\frac{4}{3}\right) hei hautanga kotahi.
x=\frac{24}{3}
Whakareatia te -6 ki te -4, ka 24.
x=8
Whakawehea te 24 ki te 3, kia riro ko 8.
