Kua tāruatia ki te papatopenga
2\left(3x+5\right)=5\left(7-x\right)
Me whakarea ngā taha e rua o te whārite ki te 10, arā, te tauraro pātahi he tino iti rawa te kitea o 5,2.
6x+10=5\left(7-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3x+5.
6x+10=35-5x
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 7-x.
6x+10+5x=35
Me tāpiri te 5x ki ngā taha e rua.
11x+10=35
Pahekotia te 6x me 5x, ka 11x.
11x=35-10
Tangohia te 10 mai i ngā taha e rua.
11x=25
Tangohia te 10 i te 35, ka 25.
x=\frac{25}{11}
Whakawehea ngā taha e rua ki te 11.
