Kua tāruatia ki te papatopenga
2x+a=\frac{11}{20}
Whakahekea te hautanga \frac{55}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
a=\frac{11}{20}-2x
Tangohia te 2x mai i ngā taha e rua.
2x+a=\frac{11}{20}
Whakahekea te hautanga \frac{55}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
2x=\frac{11}{20}-a
Tangohia te a mai i ngā taha e rua.
\frac{2x}{2}=\frac{\frac{11}{20}-a}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{\frac{11}{20}-a}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=-\frac{a}{2}+\frac{11}{40}
Whakawehe \frac{11}{20}-a ki te 2.
