7\left(2x-7\right)-2\left(1-4x\right)=22x-51
Me whakarea ngā taha e rua o te whārite ki te 14, arā, te tauraro pātahi he tino iti rawa te kitea o 2,7,14.
14x-49-2\left(1-4x\right)=22x-51
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te 2x-7.
14x-49-2+8x=22x-51
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 1-4x.
14x-51+8x=22x-51
Tangohia te 2 i te -49, ka -51.
22x-51=22x-51
Pahekotia te 14x me 8x, ka 22x.
22x-51-22x=-51
Tangohia te 22x mai i ngā taha e rua.
-51=-51
Pahekotia te 22x me -22x, ka 0.
\text{true}
Whakatauritea te -51 me te -51.
x\in \mathrm{C}
He pono tēnei mō tētahi x ahakoa.

22x-51=22x-51
Pahekotia te 14x me 8x, ka 22x.
22x-51-22x=-51
Tangohia te 22x mai i ngā taha e rua.
-51=-51
Pahekotia te 22x me -22x, ka 0.
\text{true}
Whakatauritea te -51 me te -51.
x\in \mathrm{R}
