Whakaoti mō b
b=\frac{a+3}{2}
Whakaoti mō a
a=2b-3
Tohaina
Kua tāruatia ki te papatopenga
-2b=-3-a
Tangohia te a mai i ngā taha e rua.
-2b=-a-3
He hanga arowhānui tō te whārite.
\frac{-2b}{-2}=\frac{-a-3}{-2}
Whakawehea ngā taha e rua ki te -2.
b=\frac{-a-3}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
b=\frac{a+3}{2}
Whakawehe -3-a ki te -2.
a=-3+2b
Me tāpiri te 2b ki ngā taha e rua.
