Kua tāruatia ki te papatopenga
5\left(-x\right)=3\left(x-3\right)-15
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.
5\left(-x\right)=3x-9-15
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-3.
5\left(-x\right)=3x-24
Tangohia te 15 i te -9, ka -24.
5\left(-x\right)-3x=-24
Tangohia te 3x mai i ngā taha e rua.
-5x-3x=-24
Whakareatia te 5 ki te -1, ka -5.
-8x=-24
Pahekotia te -5x me -3x, ka -8x.
x=\frac{-24}{-8}
Whakawehea ngā taha e rua ki te -8.
x=3
Whakawehea te -24 ki te -8, kia riro ko 3.
