1.3x-3.6-\frac{4}{5}x=2
Tangohia te \frac{4}{5}x mai i ngā taha e rua.
\frac{1}{2}x-3.6=2
Pahekotia te 1.3x me -\frac{4}{5}x, ka \frac{1}{2}x.
\frac{1}{2}x=2+3.6
Me tāpiri te 3.6 ki ngā taha e rua.
\frac{1}{2}x=5.6
Tāpirihia te 2 ki te 3.6, ka 5.6.
x=5.6\times 2
Me whakarea ngā taha e rua ki te 2, te tau utu o \frac{1}{2}.
x=11.2
Whakareatia te 5.6 ki te 2, ka 11.2.
