Kua tāruatia ki te papatopenga
4x+3y=-7
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 3,4,12.
4x=-7-3y
Tangohia te 3y mai i ngā taha e rua.
4x=-3y-7
He hanga arowhānui tō te whārite.
\frac{4x}{4}=\frac{-3y-7}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{-3y-7}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
4x+3y=-7
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 3,4,12.
3y=-7-4x
Tangohia te 4x mai i ngā taha e rua.
3y=-4x-7
He hanga arowhānui tō te whārite.
\frac{3y}{3}=\frac{-4x-7}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{-4x-7}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
