Question

giúp tôi câu hỏi này với 1/4 + 3/4 . x = 9/4

 

Answer 1

1/4 + 3/4 .x = 9/4

        3/4 .x  = 9/4 - 1/4

        3/4 .x  = 2

           x     = 2 : 3/4

           x     = 8/3

Nhớ k đúng cho mình nha :)))))

Answer 2

\(\frac{1}{4}+\frac{3}{4}.x=\frac{9}{4}\)

\(\frac{3}{4}.x=\frac{9}{4}-\frac{1}{4}\)

\(\frac{3}{4}.x=\frac{8}{4}=2\)

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

\(x=2.\frac{4}{3}=\frac{8}{3}\)

Vậy \(x=\frac{8}{3}\)

Answer 3

1/4 + 3/4 . x = 9/4

3/4.x=8/4

x=8/4 :3/4

x=8/3

Answer 4

\(\frac{1}{4}+\frac{3}{4}x=\frac{9}{4}\Rightarrow\frac{3}{4}x=\frac{9}{4}-\frac{1}{4}\)

\(\Rightarrow\frac{3}{4}x=2\)

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

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

Answer 5

\(\frac{1}{4}+\frac{3}{4}.x=\frac{9}{4}\)

            \(\frac{3}{4}.x=\frac{9}{4}-\frac{1}{4}\)

             \(\frac{3}{4}.x=2\)

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

                    \(x=\frac{8}{3}\)

Answer 6

\(\frac{1}{4}+\frac{3}{4}.x=\frac{9}{4}\)

\(\frac{3}{4}x=\frac{9}{4}-\frac{1}{4}\)

\(\frac{3}{4}x=\frac{8}{4}=2\)

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

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

Answer 7

\(\frac{1}{4}+\frac{3}{4}x=\frac{9}{4}\)

\(\Rightarrow\frac{3}{4}x=\frac{9}{4}-\frac{1}{4}\)

\(\Rightarrow\frac{3}{4}x=2\)

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

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

Answer 8

1/4+3/4.x=9/4   =>3/4.x=9/4-1/4

                           3/4.x=8/4

                                x=8/4:3/4

                                x=8/3
