toán thi lớp chọn cấp 2 help

x/6+1/2=3/4+0,25

Answer 1

[WTFシSnow]

\(\frac{x}{6}+\frac{1}{2}=\frac{3}{4}+0,25\)

= \(\frac{2x}{12}+\frac{6}{12}=\frac{9}{12}+\frac{3}{12}\)

=> 2x + 6 =9 + 3

= 2x + 6 = 12

2x = 6

x = 3

Answer 2

[.]

Tìm x

\(\frac{x}{6}+\frac{1}{2}=\frac{3}{4}+0,25\)

\(\frac{x}{6}+\frac{1}{2}=\frac{3}{4}+\frac{1}{4}\)

\(\frac{x}{6}+\frac{1}{2}=1\)

\(\frac{x}{6}=1-\frac{1}{2}\)

\(\frac{x}{6}=\frac{2}{2}-\frac{1}{2}\)

\(\frac{x}{6}=\frac{1}{2}\)

\(\frac{x}{6}=\frac{3}{6}\)

\(x=3\)
