x-13,1 = 7,53 x 6 21 x X = 9,45 : 0,1
x - 13,1 = 45,18 21x X = 9,45
x = 45,18 + 13,2 x = 9,45 : 21
x = 58,28 x = 4,5
vậy x = 58,28 Vậy x = 4,5
x-13,1=7,53 x 6 21x X =9,45 :0,1
x-13,1= 45,18 21x X =94,5
x=45,18+13,1 x= 94,5:21
x=58,28 x= 4,5
a, <=> x- 13,1 = 45,18
<=> x = 58 ,28
b, 21x = 94,5
<=> x =4,5
a) \(x-13,1=7,53\times6\)
\(\Rightarrow x-13,1=45,18\)
\(\Rightarrow x=45,18+13,1\)
\(\Rightarrow x=58,28\)
b) \(21\times x=9,45:0,1\)
\(\Rightarrow21\times x=94,5\)
\(\Rightarrow x=94,5:21\)
\(\Rightarrow x=4,5\)
a)x-13,1=45,18
x =45,18+13,1
x =58,28
b) 21 x x =94,5
x=94,5:21
x=4,5
a) X – 13,1 = 7,53 x 6
X – 13,1 = 45,18
X = 45,18 x 13,1
X = 591,858
b) 21 x X = 9,45 : 0,1
21 x X = 0,954
X = 0,954 : 2
X = 0,4725
