5 raruraru e ōrite ana ki:
x - \frac { x - 1 } { 2 } = 2 - \frac { x + 2 } { 4 }
Tohaina
Kua tāruatia ki te papatopenga
4x-2\left(x-1\right)=8-\left(x+2\right)
Me whakarea ngā taha e rua o te whārite ki te 4, arā, te tauraro pātahi he tino iti rawa te kitea o 2,4.
4x-2x+2=8-\left(x+2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-1.
2x+2=8-\left(x+2\right)
Pahekotia te 4x me -2x, ka 2x.
2x+2=8-x-2
Hei kimi i te tauaro o x+2, kimihia te tauaro o ia taurangi.
2x+2=6-x
Tangohia te 2 i te 8, ka 6.
2x+2+x=6
Me tāpiri te x ki ngā taha e rua.
3x+2=6
Pahekotia te 2x me x, ka 3x.
3x=6-2
Tangohia te 2 mai i ngā taha e rua.
3x=4
Tangohia te 2 i te 6, ka 4.
x=\frac{4}{3}
Whakawehea ngā taha e rua ki te 3.
Ngā Tauira
whārite tapawhā
