Question

10)   x-(-6)/15=4/24

11)   -(-6)/12+x=9/48

Answer 1

\(10,x-\dfrac{-6}{15}=\dfrac{4}{24}\)

\(x+\dfrac{6}{15}=\dfrac{1}{6}\)

\(x=\dfrac{1}{6}-\dfrac{6}{15}=\dfrac{-7}{30}\)

\(11,-\dfrac{-6}{12}+x=\dfrac{9}{48}\)

\(\dfrac{1}{2}+x=\dfrac{3}{16}\)

\(x=\dfrac{3}{16}-\dfrac{1}{2}=\dfrac{-5}{16}\)

Answer 2

\(10.\)

\(x-\dfrac{-6}{15}=\dfrac{4}{24}\)

\(\Leftrightarrow x=\dfrac{4}{24}+\dfrac{-6}{15}\)

\(\Leftrightarrow x=-\dfrac{7}{30}\)

11.\(-\dfrac{-6}{12}+x=\dfrac{9}{48}\)

\(\Leftrightarrow x=\dfrac{9}{48}+\dfrac{-6}{12}\)

\(\Leftrightarrow x=-\dfrac{5}{16}\)
