x=\frac{4}{3}x-1
Pahekotia te x me \frac{x}{3}, ka \frac{4}{3}x.
x-\frac{4}{3}x=-1
Tangohia te \frac{4}{3}x mai i ngā taha e rua.
-\frac{1}{3}x=-1
Pahekotia te x me -\frac{4}{3}x, ka -\frac{1}{3}x.
x=-\left(-3\right)
Me whakarea ngā taha e rua ki te -3, te tau utu o -\frac{1}{3}.
x=3
Whakareatia te -1 ki te -3, ka 3.
