Kua tāruatia ki te papatopenga
2x_{3}x+3x=7
Me tāpiri te 3x ki ngā taha e rua.
\left(2x_{3}+3\right)x=7
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(2x_{3}+3\right)x}{2x_{3}+3}=\frac{7}{2x_{3}+3}
Whakawehea ngā taha e rua ki te 2x_{3}+3.
x=\frac{7}{2x_{3}+3}
Mā te whakawehe ki te 2x_{3}+3 ka wetekia te whakareanga ki te 2x_{3}+3.
2xx_{3}=7-3x
He hanga arowhānui tō te whārite.
\frac{2xx_{3}}{2x}=\frac{7-3x}{2x}
Whakawehea ngā taha e rua ki te 2x.
x_{3}=\frac{7-3x}{2x}
Mā te whakawehe ki te 2x ka wetekia te whakareanga ki te 2x.
x_{3}=-\frac{3}{2}+\frac{7}{2x}
Whakawehe 7-3x ki te 2x.
