8x-32=59-5x
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te x-4.
8x-32+5x=59
Me tāpiri te 5x ki ngā taha e rua.
13x-32=59
Pahekotia te 8x me 5x, ka 13x.
13x=59+32
Me tāpiri te 32 ki ngā taha e rua.
13x=91
Tāpirihia te 59 ki te 32, ka 91.
x=\frac{91}{13}
Whakawehea ngā taha e rua ki te 13.
x=7
Whakawehea te 91 ki te 13, kia riro ko 7.
