Kua tāruatia ki te papatopenga
-5x-19=7y
Me tāpiri te 7y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
-5x=7y+19
Me tāpiri te 19 ki ngā taha e rua.
\frac{-5x}{-5}=\frac{7y+19}{-5}
Whakawehea ngā taha e rua ki te -5.
x=\frac{7y+19}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
x=\frac{-7y-19}{5}
Whakawehe 7y+19 ki te -5.
-7y-19=5x
Me tāpiri te 5x ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
-7y=5x+19
Me tāpiri te 19 ki ngā taha e rua.
\frac{-7y}{-7}=\frac{5x+19}{-7}
Whakawehea ngā taha e rua ki te -7.
y=\frac{5x+19}{-7}
Mā te whakawehe ki te -7 ka wetekia te whakareanga ki te -7.
y=\frac{-5x-19}{7}
Whakawehe 5x+19 ki te -7.
