\frac{2}{21}x=\frac{4}{9}x+1
Pahekotia te \frac{3}{7}x me -\frac{1}{3}x, ka \frac{2}{21}x.
\frac{2}{21}x-\frac{4}{9}x=1
Tangohia te \frac{4}{9}x mai i ngā taha e rua.
-\frac{22}{63}x=1
Pahekotia te \frac{2}{21}x me -\frac{4}{9}x, ka -\frac{22}{63}x.
x=1\left(-\frac{63}{22}\right)
Me whakarea ngā taha e rua ki te -\frac{63}{22}, te tau utu o -\frac{22}{63}.
x=-\frac{63}{22}
Whakareatia te 1 ki te -\frac{63}{22}, ka -\frac{63}{22}.
