Tohaina
Kua tāruatia ki te papatopenga
7a-8c=-2b
Tangohia te 2b mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
7a=-2b+8c
Me tāpiri te 8c ki ngā taha e rua.
7a=8c-2b
He hanga arowhānui tō te whārite.
\frac{7a}{7}=\frac{8c-2b}{7}
Whakawehea ngā taha e rua ki te 7.
a=\frac{8c-2b}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
2b-8c=-7a
Tangohia te 7a mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2b=-7a+8c
Me tāpiri te 8c ki ngā taha e rua.
2b=8c-7a
He hanga arowhānui tō te whārite.
\frac{2b}{2}=\frac{8c-7a}{2}
Whakawehea ngā taha e rua ki te 2.
b=\frac{8c-7a}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
b=-\frac{7a}{2}+4c
Whakawehe -7a+8c ki te 2.
