5 raruraru e ōrite ana ki:
\frac { 2 } { 5 } x + 8 = \frac { 17 } { 5 } x - 13
Tohaina
Kua tāruatia ki te papatopenga
\frac{2}{5}x+8-\frac{17}{5}x=-13
Tangohia te \frac{17}{5}x mai i ngā taha e rua.
-3x+8=-13
Pahekotia te \frac{2}{5}x me -\frac{17}{5}x, ka -3x.
-3x=-13-8
Tangohia te 8 mai i ngā taha e rua.
-3x=-21
Tangohia te 8 i te -13, ka -21.
x=\frac{-21}{-3}
Whakawehea ngā taha e rua ki te -3.
x=7
Whakawehea te -21 ki te -3, kia riro ko 7.
