Kua tāruatia ki te papatopenga
30x-5\left(2-x\right)=6\left(x+2\right)
Me whakarea ngā taha e rua o te whārite ki te 30, arā, te tauraro pātahi he tino iti rawa te kitea o 6,5.
30x-10+5x=6\left(x+2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te 2-x.
35x-10=6\left(x+2\right)
Pahekotia te 30x me 5x, ka 35x.
35x-10=6x+12
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te x+2.
35x-10-6x=12
Tangohia te 6x mai i ngā taha e rua.
29x-10=12
Pahekotia te 35x me -6x, ka 29x.
29x=12+10
Me tāpiri te 10 ki ngā taha e rua.
29x=22
Tāpirihia te 12 ki te 10, ka 22.
x=\frac{22}{29}
Whakawehea ngā taha e rua ki te 29.
