5\left(x+2\right)=3\left(x-4\right)
Me whakarea ngā taha e rua o te whārite ki te 15, arā, te tauraro pātahi he tino iti rawa te kitea o 3,5.
5x+10=3\left(x-4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+2.
5x+10=3x-12
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-4.
5x+10-3x=-12
Tangohia te 3x mai i ngā taha e rua.
2x+10=-12
Pahekotia te 5x me -3x, ka 2x.
2x=-12-10
Tangohia te 10 mai i ngā taha e rua.
2x=-22
Tangohia te 10 i te -12, ka -22.
x=\frac{-22}{2}
Whakawehea ngā taha e rua ki te 2.
x=-11
Whakawehea te -22 ki te 2, kia riro ko -11.
