\(\left(x-\frac{1}{2}\right).\frac{5}{2}+\frac{1}{2}=\frac{7}{4}\)
\(\left(x-\frac{1}{2}\right).\frac{5}{2}=\frac{7}{4}-\frac{1}{2}\)
\(\left(x-\frac{1}{2}\right).\frac{5}{2}=\frac{7}{4}-\frac{2}{4}\)
\(\left(x-\frac{1}{2}\right).\frac{5}{2}=\frac{5}{4}\)
\(\left(x-\frac{1}{2}\right)=\frac{5}{4}:\frac{5}{2}\)
\(x-\frac{1}{2}=\frac{1}{2}\)
\(x=\frac{1}{2}+\frac{1}{2}\)
\(x=1\)
(x-1/2)x 5/2=7/4-1/2
----------------= 5/4
x-1/2= 5/4 :5/2
------= 1/2
x=1/2+ 1/2
x=1
nha bn, mk nhanh nhứt
làm toán ngược nha
7/4 - 1/2 : 5/2 +1/2 = 1
dể mà
Tìm x: ( x - 1/2 ) * 5/2 + 1/2 = 7/4
( x- 1/2) * 5/2 = 7/4 - 1/2
(x-1/2) * 5/2 = 7/4 -2/4
(x-1/2) * 5/2 = 5/4
x-1/2 = 5/4 : 5/2
x-1/2 = 5/4 * 2/5
x-1/2 =1/2
x = 1/2 + 1/2
x = 1
