Linear Equation
4x-8y=9
Tohaina
Kua tāruatia ki te papatopenga
4x=9+8y
Me tāpiri te 8y ki ngā taha e rua.
4x=8y+9
He hanga arowhānui tō te whārite.
\frac{4x}{4}=\frac{8y+9}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{8y+9}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=2y+\frac{9}{4}
Whakawehe 9+8y ki te 4.
-8y=9-4x
Tangohia te 4x mai i ngā taha e rua.
\frac{-8y}{-8}=\frac{9-4x}{-8}
Whakawehea ngā taha e rua ki te -8.
y=\frac{9-4x}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
y=\frac{x}{2}-\frac{9}{8}
Whakawehe 9-4x ki te -8.
