14x+35=4x-9-x
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te 2x+5.
14x+35=3x-9
Pahekotia te 4x me -x, ka 3x.
14x+35-3x=-9
Tangohia te 3x mai i ngā taha e rua.
11x+35=-9
Pahekotia te 14x me -3x, ka 11x.
11x=-9-35
Tangohia te 35 mai i ngā taha e rua.
11x=-44
Tangohia te 35 i te -9, ka -44.
x=\frac{-44}{11}
Whakawehea ngā taha e rua ki te 11.
x=-4
Whakawehea te -44 ki te 11, kia riro ko -4.
