22x-11.2=-5\left(-0.2x+1.92\right)+21x-1.6
Whakareatia ngā taha e rua o te whārite ki te 20.
22x-11.2=x-9.6+21x-1.6
Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te -0.2x+1.92.
22x-11.2=22x-9.6-1.6
Pahekotia te x me 21x, ka 22x.
22x-11.2=22x-11.2
Tangohia te 1.6 i te -9.6, ka -11.2.
22x-11.2-22x=-11.2
Tangohia te 22x mai i ngā taha e rua.
-11.2=-11.2
Pahekotia te 22x me -22x, ka 0.
\text{true}
Whakatauritea te -11.2 me te -11.2.
x\in \mathrm{C}
He pono tēnei mō tētahi x ahakoa.
