\(2\times30-x-x=52\)
\(60-2x=52\)
\(-2x=52-60\)
\(-2x=-8\)
\(x=\left(-8\right):\left(-2\right)\)
\(x=4\)
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
2x 30 - X - X = 52. => 60 - 2X = 52
2X = 60 - 52
2X = 8
X = 8 : 2
X = 4
k mk nha!
