x_{2}x+2x_{2}=126
Whakamahia te āhuatanga tohatoha hei whakarea te x_{2} ki te x+2.
x_{2}x=126-2x_{2}
Tangohia te 2x_{2} mai i ngā taha e rua.
\frac{x_{2}x}{x_{2}}=\frac{126-2x_{2}}{x_{2}}
Whakawehea ngā taha e rua ki te x_{2}.
x=\frac{126-2x_{2}}{x_{2}}
Mā te whakawehe ki te x_{2} ka wetekia te whakareanga ki te x_{2}.
x=-2+\frac{126}{x_{2}}
Whakawehe 126-2x_{2} ki te x_{2}.
x_{2}x+2x_{2}=126
Whakamahia te āhuatanga tohatoha hei whakarea te x_{2} ki te x+2.
\left(x+2\right)x_{2}=126
Pahekotia ngā kīanga tau katoa e whai ana i te x_{2}.
\frac{\left(x+2\right)x_{2}}{x+2}=\frac{126}{x+2}
Whakawehea ngā taha e rua ki te x+2.
x_{2}=\frac{126}{x+2}
Mā te whakawehe ki te x+2 ka wetekia te whakareanga ki te x+2.
