8x-16=6x-3\left(1-5x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te x-2.
8x-16=6x-3+15x
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te 1-5x.
8x-16=21x-3
Pahekotia te 6x me 15x, ka 21x.
8x-16-21x=-3
Tangohia te 21x mai i ngā taha e rua.
-13x-16=-3
Pahekotia te 8x me -21x, ka -13x.
-13x=-3+16
Me tāpiri te 16 ki ngā taha e rua.
-13x=13
Tāpirihia te -3 ki te 16, ka 13.
x=\frac{13}{-13}
Whakawehea ngā taha e rua ki te -13.
x=-1
Whakawehea te 13 ki te -13, kia riro ko -1.
