Kua tāruatia ki te papatopenga
4x+3y=24
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.
4x=24-3y
Tangohia te 3y mai i ngā taha e rua.
\frac{4x}{4}=\frac{24-3y}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{24-3y}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=-\frac{3y}{4}+6
Whakawehe 24-3y ki te 4.
4x+3y=24
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.
3y=24-4x
Tangohia te 4x mai i ngā taha e rua.
\frac{3y}{3}=\frac{24-4x}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{24-4x}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=-\frac{4x}{3}+8
Whakawehe 24-4x ki te 3.
