Kua tāruatia ki te papatopenga
2\left(x+1\right)-3y=-9
Whakareatia ngā taha e rua o te whārite ki te 3.
2x+2-3y=-9
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+1.
2x-3y=-9-2
Tangohia te 2 mai i ngā taha e rua.
2x-3y=-11
Tangohia te 2 i te -9, ka -11.
2x=-11+3y
Me tāpiri te 3y ki ngā taha e rua.
2x=3y-11
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{3y-11}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{3y-11}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
2\left(x+1\right)-3y=-9
Whakareatia ngā taha e rua o te whārite ki te 3.
2x+2-3y=-9
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+1.
2-3y=-9-2x
Tangohia te 2x mai i ngā taha e rua.
-3y=-9-2x-2
Tangohia te 2 mai i ngā taha e rua.
-3y=-11-2x
Tangohia te 2 i te -9, ka -11.
-3y=-2x-11
He hanga arowhānui tō te whārite.
\frac{-3y}{-3}=\frac{-2x-11}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{-2x-11}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{2x+11}{3}
Whakawehe -11-2x ki te -3.
