giúp mình nha !!!
a) \(36x+12,67=489,67\)
\(\Rightarrow36x=489,67-12,67\)
\(\Rightarrow36x=477\)
\(\Rightarrow x=477:36\)
\(\Rightarrow x=13,25\)
Vậy \(x=13,25\)
b) \(x.326,63=247,37\)
\(\Rightarrow x=247,37:326,63\)
\(\Rightarrow x=0,7573401096\)
Vậy \(x=0,7573401096\)
c) \(29,5\left(x+10,25\right)=376,125\)
\(\Rightarrow x+10,25=376,125:29,5\)
\(\Rightarrow x+10,25=12,75\)
\(\Rightarrow x=12,75-10,25\)
\(\Rightarrow x=2,5\)
Vậy \(x=2,5\)
d) \(748:\left(x+31,72\right)=13,6\)
\(\Rightarrow x+31,72=748:13,6\)
\(\Rightarrow x+31,72=55\)
\(\Rightarrow x=55-31,72\)
\(\Rightarrow x=23,28\)
Vậy \(x=23,28\)

Học tốt!!!
Tìm x :
36 nhân x + 12,67 = 489,67
x nhân 326,63 + 245,37 = 429
\(36x+12,67=489,67\)
\(36x=489,67-12,67\)
\(36x=477\)
\(x=\frac{477}{36}\)
\(626,63x+245,37=429\)
\(\Rightarrow626,63x=183,63\)
\(x=\frac{183,63}{626,63}\)
\(x=...\)(dùng máy tính mà bấm nha bạn)
