Question

Answer 1

a. \(-\dfrac{3}{5}-x=-0,75\)

<=> \(-\dfrac{3}{5}+0,75=x\)

<=> \(x=\dfrac{3}{20}\)

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

<=> \(x=\dfrac{2}{5}+\dfrac{1}{3}-\dfrac{1}{3}\)

<=> \(x=\dfrac{2}{5}\)

d. \(1\dfrac{4}{5}=-0,15-x\)

<=> \(\dfrac{9}{5}=-0,15-x\)

<=> \(x=-0,15-\dfrac{9}{5}\)

<=> \(x=-\dfrac{39}{20}\)

e. \(-\dfrac{4}{7}-x=\dfrac{3}{5}-2x\)

<=> \(2x-x=\dfrac{3}{5}+\dfrac{4}{7}\)

<=> \(x=\dfrac{41}{35}\)
