Linear Equation
3x-y=7
Tohaina
Kua tāruatia ki te papatopenga
3x=7+y
Me tāpiri te y ki ngā taha e rua.
3x=y+7
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{y+7}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{y+7}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
-y=7-3x
Tangohia te 3x mai i ngā taha e rua.
\frac{-y}{-1}=\frac{7-3x}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{7-3x}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=3x-7
Whakawehe 7-3x ki te -1.
Ngā Tauira
whārite tapawhā
