Tohaina
Kua tāruatia ki te papatopenga
x+16=3x+57
Whakaarohia te whārite tuatahi. Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+19.
x+16-3x=57
Tangohia te 3x mai i ngā taha e rua.
-2x+16=57
Pahekotia te x me -3x, ka -2x.
-2x=57-16
Tangohia te 16 mai i ngā taha e rua.
-2x=41
Tangohia te 16 i te 57, ka 41.
x=-\frac{41}{2}
Whakawehea ngā taha e rua ki te -2.
x=-\frac{41}{2} y=2 z=2 a=2 b=2
Kua oti te pūnaha te whakatau.
