Kua tāruatia ki te papatopenga
8x+4=17-2x
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 2x+1.
8x+4+2x=17
Me tāpiri te 2x ki ngā taha e rua.
10x+4=17
Pahekotia te 8x me 2x, ka 10x.
10x=17-4
Tangohia te 4 mai i ngā taha e rua.
10x=13
Tangohia te 4 i te 17, ka 13.
x=\frac{13}{10}
Whakawehea ngā taha e rua ki te 10.
