Question

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

Answer 1

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

\(\dfrac{1}{3}:\left(2x-1\right)=\dfrac{-21}{4}\)

\(2x-1=\dfrac{1}{3}:\dfrac{-21}{4}\)

\(2x-1=\dfrac{-1}{21}\)

\(2x=\dfrac{-1}{21}+1\)

\(2x=\dfrac{20}{21}\)

\(x=\dfrac{20}{21}:2\)

\(x=\dfrac{10}{21}\)
