5 raruraru e ōrite ana ki:
\frac { 2 x - 1 } { 2 } + \frac { x + 2 } { 2 } = 2 x + 1
Tohaina
Kua tāruatia ki te papatopenga
2x-1+x+2=4x+2
Whakareatia ngā taha e rua o te whārite ki te 2.
3x-1+2=4x+2
Pahekotia te 2x me x, ka 3x.
3x+1=4x+2
Tāpirihia te -1 ki te 2, ka 1.
3x+1-4x=2
Tangohia te 4x mai i ngā taha e rua.
-x+1=2
Pahekotia te 3x me -4x, ka -x.
-x=2-1
Tangohia te 1 mai i ngā taha e rua.
-x=1
Tangohia te 1 i te 2, ka 1.
x=-1
Me whakarea ngā taha e rua ki te -1.
