\(2x-25=15+16\)
\(2x-25=21\)
\(2x=21+25\)
\(2x=46\)
\(x=46:2\)
\(x=23\)
Vậy \(x=23\)
2x - 25 = 15 + 16
2x - 25 = 31
2x = 31+25
2x = 56
x = 56 : 2
x = 2
2x - 25 = 15 + 16
2x - 25 = 31
2x = 31 + 25
2x = 56
x = 56 : 2
x = 28
2x - 25 = 31
2x = 31 + 25
2x = 56
x = 56 : 2
x = 28
tk mk nha
\(2x-25=15+16\)
\(2x-25=31\)
\(2x=\)\(31+25\)
\(2x=56\)
\(x=56:2\)
\(x=28\)
Tk mk nhé!Thank you!
2x-25=31
2x=31+25
2x=56
x=56:2
x=28.
các bạn .
2x - 25 = 15 +16
2x = 15 + 16 + 25
2x = 56
x = 56 : 2
x = 28
2x - 25 = 15 + 16
2x - 25 = 31
2x = 31 + 25
2x = 56
x = 28
ai k mik mik k lại
2x - 25 = 15 + 16
2x - 25 = 21
2x = 21 + 25
2x = 46
x = 46 : 2
x = 23
=> x = 23
2x- 25 = 15 + 16
=> 2x -25 = 31
=> 2x = 56
=> x= 28
đáp số x= 28
