25x+75=15x+10
Whakamahia te āhuatanga tohatoha hei whakarea te 25 ki te x+3.
25x+75-15x=10
Tangohia te 15x mai i ngā taha e rua.
10x+75=10
Pahekotia te 25x me -15x, ka 10x.
10x=10-75
Tangohia te 75 mai i ngā taha e rua.
10x=-65
Tangohia te 75 i te 10, ka -65.
x=\frac{-65}{10}
Whakawehea ngā taha e rua ki te 10.
x=-\frac{13}{2}
Whakahekea te hautanga \frac{-65}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
