Linear Equation
3x-2y=-27
Tohaina
Kua tāruatia ki te papatopenga
3x=-27+2y
Me tāpiri te 2y ki ngā taha e rua.
3x=2y-27
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{2y-27}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{2y-27}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x=\frac{2y}{3}-9
Whakawehe -27+2y ki te 3.
-2y=-27-3x
Tangohia te 3x mai i ngā taha e rua.
-2y=-3x-27
He hanga arowhānui tō te whārite.
\frac{-2y}{-2}=\frac{-3x-27}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{-3x-27}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=\frac{3x+27}{2}
Whakawehe -27-3x ki te -2.
