Transformando primeiramente as frações mistas:
3*2=6+1=7/2
1*3=3+2=5/3

 \frac{7}{2} - \frac{5}{3} *x=1
 - \frac{5}{3} *x=1- \frac{7}{2}
- \frac{5}{3} *x= \frac{2}{2} - \frac{7}{2}
- \frac{5}{3} *x= - \frac{5}{2}
x= \frac{ - \frac{5}{2}}{- \frac{5}{3} }
x= \frac{ - \frac{5}{2}}{- \frac{5}{3} }= \frac{15}{10}
x= \frac{15}{10} = \frac{3}{2}

x=3/2

Espero ter ajudado, bjs!
