-20x-5y-2x=0
Tangohia te 2x mai i ngā taha e rua.
-22x-5y=0
Pahekotia te -20x me -2x, ka -22x.
-22x=5y
Me tāpiri te 5y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
\frac{-22x}{-22}=\frac{5y}{-22}
Whakawehea ngā taha e rua ki te -22.
x=\frac{5y}{-22}
Mā te whakawehe ki te -22 ka wetekia te whakareanga ki te -22.
x=-\frac{5y}{22}
Whakawehe 5y ki te -22.
-5y=2x+20x
Me tāpiri te 20x ki ngā taha e rua.
-5y=22x
Pahekotia te 2x me 20x, ka 22x.
\frac{-5y}{-5}=\frac{22x}{-5}
Whakawehea ngā taha e rua ki te -5.
y=\frac{22x}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
y=-\frac{22x}{5}
Whakawehe 22x ki te -5.
