-3u=-15-2x
Tangohia te 2x mai i ngā taha e rua.
-3u=-2x-15
He hanga arowhānui tō te whārite.
\frac{-3u}{-3}=\frac{-2x-15}{-3}
Whakawehea ngā taha e rua ki te -3.
u=\frac{-2x-15}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
u=\frac{2x}{3}+5
Whakawehe -15-2x ki te -3.
2x=-15+3u
Me tāpiri te 3u ki ngā taha e rua.
2x=3u-15
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{3u-15}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{3u-15}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
