5 raruraru e ōrite ana ki:
\frac { x + 1 } { 2 } - 1 = 2 - \frac { 3 - x } { 4 }
Tohaina
Kua tāruatia ki te papatopenga
2\left(x+1\right)-4=8-\left(3-x\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.
2x+2-4=8-\left(3-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+1.
2x-2=8-\left(3-x\right)
Tangohia te 4 i te 2, ka -2.
2x-2=8-3-\left(-x\right)
Hei kimi i te tauaro o 3-x, kimihia te tauaro o ia taurangi.
2x-2=8-3+x
Ko te tauaro o -x ko x.
2x-2=5+x
Tangohia te 3 i te 8, ka 5.
2x-2-x=5
Tangohia te x mai i ngā taha e rua.
x-2=5
Pahekotia te 2x me -x, ka x.
x=5+2
Me tāpiri te 2 ki ngā taha e rua.
x=7
Tāpirihia te 5 ki te 2, ka 7.
