Tohaina
Kua tāruatia ki te papatopenga
-8a=1+2b
Me tāpiri te 2b ki ngā taha e rua.
-8a=2b+1
He hanga arowhānui tō te whārite.
\frac{-8a}{-8}=\frac{2b+1}{-8}
Whakawehea ngā taha e rua ki te -8.
a=\frac{2b+1}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
a=-\frac{b}{4}-\frac{1}{8}
Whakawehe 1+2b ki te -8.
-2b=1+8a
Me tāpiri te 8a ki ngā taha e rua.
-2b=8a+1
He hanga arowhānui tō te whārite.
\frac{-2b}{-2}=\frac{8a+1}{-2}
Whakawehea ngā taha e rua ki te -2.
b=\frac{8a+1}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
b=-4a-\frac{1}{2}
Whakawehe 1+8a ki te -2.
