2\left(x+2\right)+x=54
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,6.
2x+4+x=54
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+2.
3x+4=54
Pahekotia te 2x me x, ka 3x.
3x=54-4
Tangohia te 4 mai i ngā taha e rua.
3x=50
Tangohia te 4 i te 54, ka 50.
x=\frac{50}{3}
Whakawehea ngā taha e rua ki te 3.
