Kua tāruatia ki te papatopenga
2\left(x+1\right)+3=8
Me whakarea ngā taha e rua o te whārite ki te 4, arā, te tauraro pātahi he tino iti rawa te kitea o 2,4.
2x+2+3=8
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+1.
2x+5=8
Tāpirihia te 2 ki te 3, ka 5.
2x=8-5
Tangohia te 5 mai i ngā taha e rua.
2x=3
Tangohia te 5 i te 8, ka 3.
x=\frac{3}{2}
Whakawehea ngā taha e rua ki te 2.
