Tìm x:
47,212 - (\(x\) - 18,045) = 6,55
Tìm x:
47,212-(x-18,045)=6,55
47,212-(x-18,045)=6,55
=>47,212-x+18,045=6,55
=>47,212-x=6,55-17,045
=>47,212-x=-10,495
=>x=47,212-(-10,495)
=>x=47,212+10,495=57,707
Vậy x=57,707
47,212 - ( x - 18,045 ) = 6,55
x - 18,045 = 47,212 - 6,55
x - 18,045 = 40,662
x = 40,662 + 18,045
x = 58,707
47,212 - ( x - 18,045 ) = 6,55
47,212-(X-18,045)=6,55
x-18,045 =47,212-6,55
x-18,045=40,662
x =40,665+18,045
x =58,51
a) x + 3,62 = 15,4 - 0,88
b) 47,212 - x - 18,045 = 6,55
a, x+3,52=15,3-0,88
x+3,52=14,42
x =14,42-3,52
x =10,9
b, 47,212-x-18,045=6,55
47,212-x =6,55+18,046
47,212-x =24,596
x =47,212-24,596
x =22,643
x cộng 3,62 = 14,52
x = 14,52 - 3,62
x = 10,9
Tìm \(x\) biết:
3,45 x \(x\) + 6,55 x \(x\) = 2,5
\(3,45\times x+6,55\times x=2,5\\ x\times\left(3,45+6,55\right)=2,5\\ x\times10=2,5\\ x=2,5:10\\ x=0,25\)
3,45 × x + 6,55 × x = 2,5
(3,45 + 6,55) × x = 2,5
10 × x = 2,5
x = 2,5 : 10
x = 0,25
Tìm x
x+3,5=4,32+2,68
x-8,6=12,95-6,55
x + 3,5=7
=> x= 7-3,5=3,5
x-8,6=6,4
=> x=15
Tìm x biết :
\(3,45\times x+6,55\times x=2,5\)
\(3,45\times x+6,55\times x=2,5\)
\(\left(3,45+6,55\right)\times x=2,5\)
\(10\times x=2,5\)
x = 0 , 25
\(3,45\times x+6,55\times x=2,5\)
\(x\times\left(3,45+6,55\right)=2,5\)
\(x\times10=2,5\)

Tìm x
a. 1 /3 * x + 2/ 5 = 3/2
b. 3,45 * x + 6,55 * x = 2,5
c. 40 - 2 ( x - 3 ) = 16
a) 1/3 * x + 2/5 = 3/2
1/3 * x = 3/2 - 2/5
1/3 * x = 15/10 - 4/10
1/3 * x = 11/10
x = 11/10 : 1/3
x = 11/10 * 3
x = 33/10
a) x=\(\frac{33}{10}\)
b)x=\(\frac{1}{4}\)
c) x=15
3,45*x+6,55*x=10
(3,45 + 6,55) * x = 10
10 * x = 10
x = 10 : 10 = 1
hok tốt.
\(\left(3,45+6,55\right)\times x=10\)
\(\Leftrightarrow10x=10\)
\(\Leftrightarrow x=1\)
Vậy \(x=1\)
