30% x X + X = 52
tim X biet : 30% x X + X = 52
Ta có: 30%xX+X=52
nên 130%xX=52
X=52:130%=40
Vậy X= 40
40 bạn ơi
30% x X + X = 52
30 % x X + X x 100% = 52
130 % x X = 52
X = 52 x 100 / 130
X = 40
nhớ k cho mình nhé
30% x X + X =52
X + X = 52 : 30%
2X= 520/3
X = 520/3 :2
X = 520/3 x1/2
X = 260/3
2 x 30 - X - X=52
\(2\times30-x-x=52\)
\(60-2x=52\)
\(-2x=52-60\)
\(-2x=-8\)
\(x=\left(-8\right):\left(-2\right)\)
\(x=4\)
Vậy \(x=4\)
2 x 30 - X - X = 52
60 = 52 + X x 2
60 - 52 = X x 2
8 = X x 2
8 : 2 = X
4 = X
2 x 30 - x - x = 52
60 - x x 2 = 52
x x 2 = 60 - 52
x x 2 = 8
x = 8 : 2
x = 4
Tim X biet : 30% x X +X =52
30% * x + x= 52
\(30\%\cdot x+x=52\)
\(\left(\frac{3}{10}+1\right)x=52\)
\(\frac{13}{10}x=52\)
\(x=40\)
\(\text{Ta có: 30% * x + x= 52 }\)
\(\Rightarrow\frac{3}{10}x+x=52\)
\(\Rightarrow\left(\frac{3}{10}+1\right)x=52\)
\(\Rightarrow\frac{13}{10}x=52\)
Đổi 30% = 3/10
=> 3/10 * x + x = 52
=> x * ( 3/10 + 1 ) = 52
=> x * 13/10 = 52
=> x = 52 : 13/10
=> x = 10
Vậy x = 40
30%×X+X = 52
30% x X + X= 52
30% x X + X x 100%=52
130% x X = 52
X= 52 x 100/130
X= 40
30%x+x=52
30%x + x = 52
0,3 . x + x . 1 = 52
x . \(\left(0,3+1\right)\) = 52
x . 1,3 = 52
x = \(52\div1,3\)
x = 40
Vậy x = 40
