Kua tāruatia ki te papatopenga
|\frac{1}{2}x-\frac{9}{2}|=4
Whakawehea ia wā o x-9 ki te 2, kia riro ko \frac{1}{2}x-\frac{9}{2}.
\frac{1}{2}x-\frac{9}{2}=4 \frac{1}{2}x-\frac{9}{2}=-4
Whakamahia te tautuhinga o te uara pū.
\frac{1}{2}x=\frac{17}{2} \frac{1}{2}x=\frac{1}{2}
Me tāpiri \frac{9}{2} ki ngā taha e rua o te whārite.
x=17 x=1
Me whakarea ngā taha e rua ki te 2.
