10\left(x+6\right)+8\left(x-3\right)=5\left(5x-4\right)
Me whakarea ngā taha e rua o te whārite ki te 40, arā, te tauraro pātahi he tino iti rawa te kitea o 4,5,8.
10x+60+8\left(x-3\right)=5\left(5x-4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 10 ki te x+6.
10x+60+8x-24=5\left(5x-4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te x-3.
18x+60-24=5\left(5x-4\right)
Pahekotia te 10x me 8x, ka 18x.
18x+36=5\left(5x-4\right)
Tangohia te 24 i te 60, ka 36.
18x+36=25x-20
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 5x-4.
18x+36-25x=-20
Tangohia te 25x mai i ngā taha e rua.
-7x+36=-20
Pahekotia te 18x me -25x, ka -7x.
-7x=-20-36
Tangohia te 36 mai i ngā taha e rua.
-7x=-56
Tangohia te 36 i te -20, ka -56.
x=\frac{-56}{-7}
Whakawehea ngā taha e rua ki te -7.
x=8
Whakawehea te -56 ki te -7, kia riro ko 8.
