Kua tāruatia ki te papatopenga
0\left(2x+3\right)-x=3x-138
Whakareatia te 0 ki te 2, ka 0.
0-x=3x-138
Ko te tau i whakarea ki te kore ka hua ko te kore.
-x=3x-138
Ko te tau i tāpiria he kore ka hua koia tonu.
-x-3x=-138
Tangohia te 3x mai i ngā taha e rua.
-4x=-138
Pahekotia te -x me -3x, ka -4x.
x=\frac{-138}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{69}{2}
Whakahekea te hautanga \frac{-138}{-4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
