2x-3y=42
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,2.
2x=42+3y
Me tāpiri te 3y ki ngā taha e rua.
2x=3y+42
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{3y+42}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{3y+42}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{3y}{2}+21
Whakawehe 42+3y ki te 2.
2x-3y=42
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,2.
-3y=42-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{-3y}{-3}=\frac{42-2x}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{42-2x}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{2x}{3}-14
Whakawehe 42-2x ki te -3.
