Tohaina
Kua tāruatia ki te papatopenga
3x=40+y
Me tāpiri te y ki ngā taha e rua.
3x=y+40
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{y+40}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{y+40}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
-y=40-3x
Tangohia te 3x mai i ngā taha e rua.
\frac{-y}{-1}=\frac{40-3x}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{40-3x}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=3x-40
Whakawehe 40-3x ki te -1.
