Kua tāruatia ki te papatopenga
\frac{15}{8}x=42
Pahekotia te x me \frac{7}{8}x, ka \frac{15}{8}x.
x=42\times \frac{8}{15}
Me whakarea ngā taha e rua ki te \frac{8}{15}, te tau utu o \frac{15}{8}.
x=\frac{42\times 8}{15}
Tuhia te 42\times \frac{8}{15} hei hautanga kotahi.
x=\frac{336}{15}
Whakareatia te 42 ki te 8, ka 336.
x=\frac{112}{5}
Whakahekea te hautanga \frac{336}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
