125y+3x-13x=-30
Tangohia te 13x mai i ngā taha e rua.
125y-10x=-30
Pahekotia te 3x me -13x, ka -10x.
-10x=-30-125y
Tangohia te 125y mai i ngā taha e rua.
-10x=-125y-30
He hanga arowhānui tō te whārite.
\frac{-10x}{-10}=\frac{-125y-30}{-10}
Whakawehea ngā taha e rua ki te -10.
x=\frac{-125y-30}{-10}
Mā te whakawehe ki te -10 ka wetekia te whakareanga ki te -10.
x=\frac{25y}{2}+3
Whakawehe -30-125y ki te -10.
125y=13x-30-3x
Tangohia te 3x mai i ngā taha e rua.
125y=10x-30
Pahekotia te 13x me -3x, ka 10x.
\frac{125y}{125}=\frac{10x-30}{125}
Whakawehea ngā taha e rua ki te 125.
y=\frac{10x-30}{125}
Mā te whakawehe ki te 125 ka wetekia te whakareanga ki te 125.
y=\frac{2x-6}{25}
Whakawehe -30+10x ki te 125.
