Tohaina
Kua tāruatia ki te papatopenga
-2a+5=3e^{2}
Me tāpiri te 3e^{2} ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
-2a=3e^{2}-5
Tangohia te 5 mai i ngā taha e rua.
\frac{-2a}{-2}=\frac{3e^{2}-5}{-2}
Whakawehea ngā taha e rua ki te -2.
a=\frac{3e^{2}-5}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
a=\frac{-3e^{2}+5}{2}
Whakawehe 3e^{2}-5 ki te -2.
