Answer 1

[Nguyễn Lê Phước Thịnh]

a: \(y-\dfrac{4}{5}=2-\dfrac{1}{3}\)

=>\(y-\dfrac{4}{5}=\dfrac{5}{3}\)

=>\(y=\dfrac{5}{3}+\dfrac{4}{5}=\dfrac{25+12}{15}=\dfrac{37}{15}\)

b: \(\dfrac{12}{7}-y=\dfrac{1}{3}+2\)

=>\(\dfrac{12}{7}-y=\dfrac{7}{3}\)

=>\(y=\dfrac{12}{7}-\dfrac{7}{3}=\dfrac{36-49}{21}=\dfrac{-13}{21}\)

c: \(y:\dfrac{5}{6}=1+\dfrac{7}{2}\)

=>\(y:\dfrac{5}{6}=\dfrac{9}{2}\)

=>\(y=\dfrac{9}{2}\times\dfrac{5}{6}=\dfrac{45}{12}=3,75\)

d: \(3,6\times y=2,52:10\)

=>\(3,6\times y=0,252\)

=>y=0,252:3,6=0,07

e: 1,05:y+1,4=3,5

=>1,05:y=2,1

=>y=1,05:2,1=0,5

f: y-4,7=24,9+1,6

=>y-4,7=26,5

=>y=26,5+4,7=31,2
