Answer 1

a; \(\dfrac{x}{8}\) = \(\dfrac{3}{4}\) + \(\dfrac{-5}{8}\)

     \(\dfrac{x}{8}\) =  \(\dfrac{1}{8}\)

     \(x\) =  \(\dfrac{1}{8}\) \(\times\) 8 

      \(x\) = 1

b;  \(\dfrac{x}{12}\) = \(\dfrac{3}{4}\) + \(\dfrac{-2}{3}\)

     \(\dfrac{x}{12}\) =  \(\dfrac{1}{12}\)

       \(x\) = \(\dfrac{1}{12}\) \(\times\) 12

       \(x\) = 1

      

Answer 2

c; 1 + \(\dfrac{11}{3}\) = \(\dfrac{24}{x}\)

    \(\dfrac{14}{3}\)      =  \(\dfrac{24}{x}\)

     \(x\)        = 24 :  \(\dfrac{14}{3}\) 

      \(x\)       = \(\dfrac{36}{7}\)

d; \(\dfrac{x}{6}\) - \(\dfrac{3}{4}\) = \(\dfrac{1}{12}\)

     \(\dfrac{x}{6}\)      = \(\dfrac{1}{12}\) + \(\dfrac{3}{4}\)

      \(\dfrac{x}{6}\)     = \(\dfrac{5}{6}\)

      \(x\)    = \(\dfrac{5}{6}\) \(\times\) 6

       \(x\)   = 5
