Question

tìm x

A )   1- ( 3/4 + x  -2/3 ) : 4/5 =0

 

Answer 1

1 - (3/4 + x - 2/3) : 4/5 = 0

=> (9/12 + x - 8/12) . 5/4 = 1 - 0

=> (1/12 + x) . 5/4 = 1

=> 1/12 + x = 1 : 5/4

=> 1/12 + x = 4/5

=> x = 4/5 - 1/12

=> x = 48/60 - 5/60

=> x = 43/60

Answer 2

\(\Rightarrow\left(\frac{3}{4}+x-\frac{2}{3}\right):\frac{4}{5}=1-0\)

\(\Rightarrow\frac{3}{4}+x-\frac{2}{3}=1.\frac{4}{5}\)

\(\Rightarrow\frac{3}{4}+x=\frac{4}{5}+\frac{1}{3}\)

\(\Rightarrow x=\frac{17}{15}-\frac{3}{4}\)

\(\Rightarrow x=\frac{43}{60}\)
