5x-5+16\left(2x+3\right)=3\left(2x-7\right)-x
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-1.
5x-5+32x+48=3\left(2x-7\right)-x
Whakamahia te āhuatanga tohatoha hei whakarea te 16 ki te 2x+3.
37x-5+48=3\left(2x-7\right)-x
Pahekotia te 5x me 32x, ka 37x.
37x+43=3\left(2x-7\right)-x
Tāpirihia te -5 ki te 48, ka 43.
37x+43=6x-21-x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x-7.
37x+43=5x-21
Pahekotia te 6x me -x, ka 5x.
37x+43-5x=-21
Tangohia te 5x mai i ngā taha e rua.
32x+43=-21
Pahekotia te 37x me -5x, ka 32x.
32x=-21-43
Tangohia te 43 mai i ngā taha e rua.
32x=-64
Tangohia te 43 i te -21, ka -64.
x=\frac{-64}{32}
Whakawehea ngā taha e rua ki te 32.
x=-2
Whakawehea te -64 ki te 32, kia riro ko -2.
