Question

a) -2/3 x + 5/8 = -7/12

b) -3/4 - ( x + 1/2) = 5/3

 

Answer 1

a) \(-\dfrac{2}{3}x+\dfrac{5}{8}=-\dfrac{7}{12}\)

\(-\dfrac{2}{3}x=-\dfrac{7}{12}-\dfrac{5}{8}=-\dfrac{29}{24}\)

\(x=\dfrac{-29}{24}:\dfrac{-2}{3}=\dfrac{29}{16}\)

b) \(-\dfrac{3}{4}-\left(x+\dfrac{1}{2}\right)=\dfrac{5}{3}\)

\(x+\dfrac{1}{2}=-\dfrac{3}{4}-\dfrac{5}{3}=-\dfrac{29}{12}\)

\(x=-\dfrac{29}{12}-\dfrac{1}{2}=-\dfrac{35}{12}\)
