Kua tāruatia ki te papatopenga
-2\times 2x+y-1=-12
Me whakarea ngā taha e rua o te whārite ki te 10, arā, te tauraro pātahi he tino iti rawa te kitea o 5,10.
-4x+y-1=-12
Whakareatia te -2 ki te 2, ka -4.
-4x-1=-12-y
Tangohia te y mai i ngā taha e rua.
-4x=-12-y+1
Me tāpiri te 1 ki ngā taha e rua.
-4x=-11-y
Tāpirihia te -12 ki te 1, ka -11.
-4x=-y-11
He hanga arowhānui tō te whārite.
\frac{-4x}{-4}=\frac{-y-11}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{-y-11}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
x=\frac{y+11}{4}
Whakawehe -11-y ki te -4.
-2\times 2x+y-1=-12
Me whakarea ngā taha e rua o te whārite ki te 10, arā, te tauraro pātahi he tino iti rawa te kitea o 5,10.
-4x+y-1=-12
Whakareatia te -2 ki te 2, ka -4.
y-1=-12+4x
Me tāpiri te 4x ki ngā taha e rua.
y=-12+4x+1
Me tāpiri te 1 ki ngā taha e rua.
y=-11+4x
Tāpirihia te -12 ki te 1, ka -11.
