Kua tāruatia ki te papatopenga
6\left(x-1\right)+15\left(x-2\right)=10x
Me whakarea ngā taha e rua o te whārite ki te 30, arā, te tauraro pātahi he tino iti rawa te kitea o 5,2,3.
6x-6+15\left(x-2\right)=10x
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te x-1.
6x-6+15x-30=10x
Whakamahia te āhuatanga tohatoha hei whakarea te 15 ki te x-2.
21x-6-30=10x
Pahekotia te 6x me 15x, ka 21x.
21x-36=10x
Tangohia te 30 i te -6, ka -36.
21x-36-10x=0
Tangohia te 10x mai i ngā taha e rua.
11x-36=0
Pahekotia te 21x me -10x, ka 11x.
11x=36
Me tāpiri te 36 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{36}{11}
Whakawehea ngā taha e rua ki te 11.
