Kua tāruatia ki te papatopenga
12-\left(5y+4x\right)=18
Whakareatia ngā taha e rua o te whārite ki te 3.
12-5y-4x=18
Hei kimi i te tauaro o 5y+4x, kimihia te tauaro o ia taurangi.
-5y-4x=18-12
Tangohia te 12 mai i ngā taha e rua.
-5y-4x=6
Tangohia te 12 i te 18, ka 6.
-4x=6+5y
Me tāpiri te 5y ki ngā taha e rua.
-4x=5y+6
He hanga arowhānui tō te whārite.
\frac{-4x}{-4}=\frac{5y+6}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{5y+6}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
x=-\frac{5y}{4}-\frac{3}{2}
Whakawehe 6+5y ki te -4.
12-\left(5y+4x\right)=18

-5y-4x=18-12
Tangohia te 12 mai i ngā taha e rua.
-5y-4x=6
Tangohia te 12 i te 18, ka 6.
-5y=6+4x
Me tāpiri te 4x ki ngā taha e rua.
-5y=4x+6
He hanga arowhānui tō te whārite.
\frac{-5y}{-5}=\frac{4x+6}{-5}
Whakawehea ngā taha e rua ki te -5.
y=\frac{4x+6}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
y=\frac{-4x-6}{5}
Whakawehe 6+4x ki te -5.
