Kua tāruatia ki te papatopenga
2\left(-2\right)x+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=13-y
Tāpirihia te 12 ki te 1, ka 13.
\frac{-4x}{-4}=\frac{13-y}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{13-y}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
x=\frac{y-13}{4}
Whakawehe 13-y ki te -4.
2\left(-2\right)x+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=13+4x
Tāpirihia te 12 ki te 1, ka 13.
