Kua tāruatia ki te papatopenga
5\times 3\left(x-1\right)-2\left(x-2\right)=1510
Me whakarea ngā taha e rua o te whārite ki te 10, arā, te tauraro pātahi he tino iti rawa te kitea o 2,5.
15\left(x-1\right)-2\left(x-2\right)=1510
Whakareatia te 5 ki te 3, ka 15.
15x-15-2\left(x-2\right)=1510
Whakamahia te āhuatanga tohatoha hei whakarea te 15 ki te x-1.
15x-15-2x+4=1510
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-2.
13x-15+4=1510
Pahekotia te 15x me -2x, ka 13x.
13x-11=1510
Tāpirihia te -15 ki te 4, ka -11.
13x=1510+11
Me tāpiri te 11 ki ngā taha e rua.
13x=1521
Tāpirihia te 1510 ki te 11, ka 1521.
x=\frac{1521}{13}
Whakawehea ngā taha e rua ki te 13.
x=117
Whakawehea te 1521 ki te 13, kia riro ko 117.
