d=7
Tohaina
Kua tāruatia ki te papatopenga
6x+3-4x=0
Whakaarohia te whārite tuatahi. Tangohia te 4x mai i ngā taha e rua.
2x+3=0
Pahekotia te 6x me -4x, ka 2x.
2x=-3
Tangohia te 3 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=-\frac{3}{2}
Whakawehea ngā taha e rua ki te 2.
x=-\frac{3}{2} y=7 z=7 a=7 b=7 c=7 d=7
Kua oti te pūnaha te whakatau.
