Question

tìm x:

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

Answer 1

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

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

              \(x=0\)

Answer 2

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

\(\frac{10}{4}+x=\frac{5}{2}\)

\(x=\frac{5}{2}-\frac{10}{4}\)

\(x=0\)

Answer 3

10/4+x=5/2

x=5/2-5/2=0

Answer 4

= 0

các bạn k mình nha

Answer 5

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

\(\frac{10}{4}+x=\frac{5}{2}\)

\(x=\frac{5}{2}-\frac{10}{4}\)

\(x=0\)

Answer 6

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

x=\(\frac{5}{2}-\frac{10}{4}\)

x=0
