[tex] \frac{1}{4} y+ 1 \frac{1}{2} + 2 - 1 \frac{3}{4} y-12 [/tex]
It is easy to calculate when we convert all the mixed fractions to proper fractions
[tex] \frac{1}{4} y+ \frac{3}{2} + 2 - \frac{7}{4} y-12 [/tex]
lets add the similar terms
[tex] (\frac{1}{4} -\frac{7}{4} )y + \frac{3}{2} +(2-12) [/tex]
[tex] \frac{-3}{2} y + \frac{3}{2} -10 [/tex]
[tex] \frac{-3}{2} y - \frac{17}{2} [/tex]
-1.5y-8.5
As we cannot simplify this further, this will be our simplified answer
