5 raruraru e ōrite ana ki:
3 \cdot ( 2 x - 1 ) - 2 \cdot ( x - 3 ) = 5 - ( x - 5 )
Tohaina
Kua tāruatia ki te papatopenga
6x-3-2\left(x-3\right)=5-\left(x-5\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x-1.
6x-3-2x+6=5-\left(x-5\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-3.
4x-3+6=5-\left(x-5\right)
Pahekotia te 6x me -2x, ka 4x.
4x+3=5-\left(x-5\right)
Tāpirihia te -3 ki te 6, ka 3.
4x+3=5-x-\left(-5\right)
Hei kimi i te tauaro o x-5, kimihia te tauaro o ia taurangi.
4x+3=5-x+5
Ko te tauaro o -5 ko 5.
4x+3=10-x
Tāpirihia te 5 ki te 5, ka 10.
4x+3+x=10
Me tāpiri te x ki ngā taha e rua.
5x+3=10
Pahekotia te 4x me x, ka 5x.
5x=10-3
Tangohia te 3 mai i ngā taha e rua.
5x=7
Tangohia te 3 i te 10, ka 7.
x=\frac{7}{5}
Whakawehea ngā taha e rua ki te 5.
