Kua tāruatia ki te papatopenga
1.5x=15-3y
Tangohia te 3y mai i ngā taha e rua.
\frac{1.5x}{1.5}=\frac{15-3y}{1.5}
Whakawehea ngā taha e rua o te whārite ki te 1.5, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{15-3y}{1.5}
Mā te whakawehe ki te 1.5 ka wetekia te whakareanga ki te 1.5.
x=10-2y
Whakawehe 15-3y ki te 1.5 mā te whakarea 15-3y ki te tau huripoki o 1.5.
3y=15-1.5x
Tangohia te 1.5x mai i ngā taha e rua.
3y=-\frac{3x}{2}+15
He hanga arowhānui tō te whārite.
\frac{3y}{3}=\frac{-\frac{3x}{2}+15}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{-\frac{3x}{2}+15}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=-\frac{x}{2}+5
Whakawehe 15-\frac{3x}{2} ki te 3.
