\frac{6}{5}x+\frac{7}{16}-x=-\frac{3}{2}
Tangohia te x mai i ngā taha e rua.
\frac{1}{5}x+\frac{7}{16}=-\frac{3}{2}
Pahekotia te \frac{6}{5}x me -x, ka \frac{1}{5}x.
\frac{1}{5}x=-\frac{3}{2}-\frac{7}{16}
Tangohia te \frac{7}{16} mai i ngā taha e rua.
\frac{1}{5}x=-\frac{24}{16}-\frac{7}{16}
Ko te maha noa iti rawa atu o 2 me 16 ko 16. Me tahuri -\frac{3}{2} me \frac{7}{16} ki te hautau me te tautūnga 16.
\frac{1}{5}x=\frac{-24-7}{16}
Tā te mea he rite te tauraro o -\frac{24}{16} me \frac{7}{16}, me tango rāua mā te tango i ō raua taurunga.
\frac{1}{5}x=-\frac{31}{16}
Tangohia te 7 i te -24, ka -31.
x=-\frac{31}{16}\times 5
Me whakarea ngā taha e rua ki te 5, te tau utu o \frac{1}{5}.
x=\frac{-31\times 5}{16}
Tuhia te -\frac{31}{16}\times 5 hei hautanga kotahi.
x=\frac{-155}{16}
Whakareatia te -31 ki te 5, ka -155.
x=-\frac{155}{16}
Ka taea te hautanga \frac{-155}{16} te tuhi anō ko -\frac{155}{16} mā te tango i te tohu tōraro.
