Kua tāruatia ki te papatopenga
3x+3+\frac{3}{4}x=6
Me tāpiri te \frac{3}{4}x ki ngā taha e rua.
\frac{15}{4}x+3=6
Pahekotia te 3x me \frac{3}{4}x, ka \frac{15}{4}x.
\frac{15}{4}x=6-3
Tangohia te 3 mai i ngā taha e rua.
\frac{15}{4}x=3
Tangohia te 3 i te 6, ka 3.
x=3\times \frac{4}{15}
Me whakarea ngā taha e rua ki te \frac{4}{15}, te tau utu o \frac{15}{4}.
x=\frac{3\times 4}{15}
Tuhia te 3\times \frac{4}{15} hei hautanga kotahi.
x=\frac{12}{15}
Whakareatia te 3 ki te 4, ka 12.
x=\frac{4}{5}
Whakahekea te hautanga \frac{12}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
