Question

TÌm x?

Answer 1

\(a,\dfrac{1}{5}.\left(-\dfrac{53}{5}\right)+5x-x=-\dfrac{2}{3}\\ -\dfrac{53}{25}+4x=-\dfrac{2}{3}\\ 4x=-\dfrac{2}{3}-\left(-\dfrac{53}{25}\right)\\ 4x=\dfrac{109}{75}\\ x=\dfrac{109}{300}\\ 10,-\dfrac{3}{2}.\dfrac{29}{6}+4x-2=1\\ -\dfrac{29}{4}+4x-2=1\\ 4x-\dfrac{37}{4}=1\\ 4x=1+\dfrac{37}{4}\\ 4x=\dfrac{41}{4}\\ x=\dfrac{41}{16}\)

Answer 2

9: =>-3/25-2+5x=x-2/3

=>5x-53/25=x-2/3

=>4x=109/75

=>x=109/300

10: =>-15/2+1/4+4x-2=1

=>4x-37/4=1

=>4x=41/4

hay x=41/16
