15-14+10x=2x+5-3x
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 7-5x.
1+10x=2x+5-3x
Tangohia te 14 i te 15, ka 1.
1+10x=-x+5
Pahekotia te 2x me -3x, ka -x.
1+10x+x=5
Me tāpiri te x ki ngā taha e rua.
1+11x=5
Pahekotia te 10x me x, ka 11x.
11x=5-1
Tangohia te 1 mai i ngā taha e rua.
11x=4
Tangohia te 1 i te 5, ka 4.
x=\frac{4}{11}
Whakawehea ngā taha e rua ki te 11.
