Kua tāruatia ki te papatopenga
-2x=39+5y
Me tāpiri te 5y ki ngā taha e rua.
-2x=5y+39
He hanga arowhānui tō te whārite.
\frac{-2x}{-2}=\frac{5y+39}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{5y+39}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{-5y-39}{2}
Whakawehe 39+5y ki te -2.
-5y=39+2x
Me tāpiri te 2x ki ngā taha e rua.
-5y=2x+39
He hanga arowhānui tō te whārite.
\frac{-5y}{-5}=\frac{2x+39}{-5}
Whakawehea ngā taha e rua ki te -5.
y=\frac{2x+39}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
y=\frac{-2x-39}{5}
Whakawehe 39+2x ki te -5.
