Kua tāruatia ki te papatopenga
\frac{3}{4}x-4-\frac{7}{8}x=0
Tangohia te \frac{7}{8}x mai i ngā taha e rua.
-\frac{1}{8}x-4=0
Pahekotia te \frac{3}{4}x me -\frac{7}{8}x, ka -\frac{1}{8}x.
-\frac{1}{8}x=4
Me tāpiri te 4 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=4\left(-8\right)
Me whakarea ngā taha e rua ki te -8, te tau utu o -\frac{1}{8}.
x=-32
Whakareatia te 4 ki te -8, ka -32.
