Linear Equation
2 x - y = 6
Tohaina
Kua tāruatia ki te papatopenga
2x=6+y
Me tāpiri te y ki ngā taha e rua.
2x=y+6
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{y+6}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{y+6}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{y}{2}+3
Whakawehe 6+y ki te 2.
-y=6-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{-y}{-1}=\frac{6-2x}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{6-2x}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=2x-6
Whakawehe 6-2x ki te -1.
