2+3x-78=92-x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-26.
-76+3x=92-x
Tangohia te 78 i te 2, ka -76.
-76+3x+x=92
Me tāpiri te x ki ngā taha e rua.
-76+4x=92
Pahekotia te 3x me x, ka 4x.
4x=92+76
Me tāpiri te 76 ki ngā taha e rua.
4x=168
Tāpirihia te 92 ki te 76, ka 168.
x=\frac{168}{4}
Whakawehea ngā taha e rua ki te 4.
x=42
Whakawehea te 168 ki te 4, kia riro ko 42.
