15\left(x-6\right)-10\left(x-4\right)=60-6x
Me whakarea ngā taha e rua o te whārite ki te 60, arā, te tauraro pātahi he tino iti rawa te kitea o 4,6,10.
15x-90-10\left(x-4\right)=60-6x
Whakamahia te āhuatanga tohatoha hei whakarea te 15 ki te x-6.
15x-90-10x+40=60-6x
Whakamahia te āhuatanga tohatoha hei whakarea te -10 ki te x-4.
5x-90+40=60-6x
Pahekotia te 15x me -10x, ka 5x.
5x-50=60-6x
Tāpirihia te -90 ki te 40, ka -50.
5x-50+6x=60
Me tāpiri te 6x ki ngā taha e rua.
11x-50=60
Pahekotia te 5x me 6x, ka 11x.
11x=60+50
Me tāpiri te 50 ki ngā taha e rua.
11x=110
Tāpirihia te 60 ki te 50, ka 110.
x=\frac{110}{11}
Whakawehea ngā taha e rua ki te 11.
x=10
Whakawehea te 110 ki te 11, kia riro ko 10.
