Kua tāruatia ki te papatopenga
x-4+54-2\left(x-27\right)=36
Whakareatia ngā taha e rua o te whārite ki te 2.
x+50-2\left(x-27\right)=36
Tāpirihia te -4 ki te 54, ka 50.
x+50-2x+54=36
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-27.
-x+50+54=36
Pahekotia te x me -2x, ka -x.
-x+104=36
Tāpirihia te 50 ki te 54, ka 104.
-x=36-104
Tangohia te 104 mai i ngā taha e rua.
-x=-68
Tangohia te 104 i te 36, ka -68.
x=68
Me whakarea ngā taha e rua ki te -1.
