Question

tìm x trong tỉ lệ thức 

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

giúp mk vs ạ mk cảm ơn

 

Answer 1

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

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

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

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

                \(x=-\frac{3}{8}\)

Answer 2

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

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

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

\(x\)\(=\)\(\frac{-3}{8}\)

Answer 3

x=-0,375

Answer 4

1/2+2/3 x=1/4

2/3x=1/4-1/2

2/3x=-1/4

X=-1/4:2/3

X=-3/8
