2\times 2x-10x=x-175
Me whakarea ngā taha e rua o te whārite ki te 10, arā, te tauraro pātahi he tino iti rawa te kitea o 5,10,2.
4x-10x=x-175
Whakareatia te 2 ki te 2, ka 4.
-6x=x-175
Pahekotia te 4x me -10x, ka -6x.
-6x-x=-175
Tangohia te x mai i ngā taha e rua.
-7x=-175
Pahekotia te -6x me -x, ka -7x.
x=\frac{-175}{-7}
Whakawehea ngā taha e rua ki te -7.
x=25
Whakawehea te -175 ki te -7, kia riro ko 25.
