2\left(\frac{x}{2}-\frac{2\times 2}{2}\right)-3\left(x+1\right)
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 2 ki te \frac{2}{2}.
2\times \frac{x-2\times 2}{2}-3\left(x+1\right)
Tā te mea he rite te tauraro o \frac{x}{2} me \frac{2\times 2}{2}, me tango rāua mā te tango i ō raua taurunga.
2\times \frac{x-4}{2}-3\left(x+1\right)
Mahia ngā whakarea i roto o x-2\times 2.
x-4-3\left(x+1\right)
Me whakakore te 2 me te 2.
x-4-3x-3
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x+1.
-2x-4-3
Pahekotia te x me -3x, ka -2x.
-2x-7
Tangohia te 3 i te -4, ka -7.
