Kua tāruatia ki te papatopenga
-\frac{23}{2}x-y=7
Ka taea te hautanga \frac{-23}{2} te tuhi anō ko -\frac{23}{2} mā te tango i te tohu tōraro.
-\frac{23}{2}x=7+y
Me tāpiri te y ki ngā taha e rua.
-\frac{23}{2}x=y+7
He hanga arowhānui tō te whārite.
\frac{-\frac{23}{2}x}{-\frac{23}{2}}=\frac{y+7}{-\frac{23}{2}}
Whakawehea ngā taha e rua o te whārite ki te -\frac{23}{2}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{y+7}{-\frac{23}{2}}
Mā te whakawehe ki te -\frac{23}{2} ka wetekia te whakareanga ki te -\frac{23}{2}.
x=\frac{-2y-14}{23}
Whakawehe 7+y ki te -\frac{23}{2} mā te whakarea 7+y ki te tau huripoki o -\frac{23}{2}.
-\frac{23}{2}x-y=7
Ka taea te hautanga \frac{-23}{2} te tuhi anō ko -\frac{23}{2} mā te tango i te tohu tōraro.
-y=7+\frac{23}{2}x
Me tāpiri te \frac{23}{2}x ki ngā taha e rua.
-y=\frac{23x}{2}+7
He hanga arowhānui tō te whārite.
\frac{-y}{-1}=\frac{\frac{23x}{2}+7}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{\frac{23x}{2}+7}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=-\frac{23x}{2}-7
Whakawehe 7+\frac{23x}{2} ki te -1.
