\frac{1-3}{2}+7x-4x=-1+6+4x+10
Tā te mea he rite te tauraro o \frac{1}{2} me \frac{3}{2}, me tango rāua mā te tango i ō raua taurunga.
\frac{-2}{2}+7x-4x=-1+6+4x+10
Tangohia te 3 i te 1, ka -2.
-1+7x-4x=-1+6+4x+10
Whakawehea te -2 ki te 2, kia riro ko -1.
-1+3x=-1+6+4x+10
Pahekotia te 7x me -4x, ka 3x.
-1+3x=5+4x+10
Tāpirihia te -1 ki te 6, ka 5.
-1+3x=15+4x
Tāpirihia te 5 ki te 10, ka 15.
-1+3x-4x=15
Tangohia te 4x mai i ngā taha e rua.
-1-x=15
Pahekotia te 3x me -4x, ka -x.
-x=15+1
Me tāpiri te 1 ki ngā taha e rua.
-x=16
Tāpirihia te 15 ki te 1, ka 16.
x=-16
Me whakarea ngā taha e rua ki te -1.
