Question

Tìm x 
a) -3/2 - 2x + 3/4 = -1 
b) ( -2/3 x - 3/5 ) . ( 3/-2 - 10/3 ) = 2/5 
c) x/2 - ( 3x/5 - 13/5 = -( 7/5 + 7/10 ) 
d) 2x-3/3 + -3/2 = 5-3x/6 - 1/3 
Ai biết câu nào giải trước giúp e, em cảm ơn 

Answer 1

\(a,\frac{-3}{2}-2x+\frac{3}{4}=-1\)

\(\frac{-3}{2}-2x=-1-\frac{3}{4}\)

\(\frac{-3}{2}-2x=\frac{-7}{4}\)

\(2x=\frac{-7}{4}+\frac{-3}{2}\)

\(2x=\frac{-13}{4}\)

\(x=\frac{-13}{4}:2\)

\(x=\frac{-13}{4}.\frac{1}{2}\)

\(x=\frac{-13}{8}\)
