x+23=56
12+34+56+78+56=45+x-23=1234-x+56
Tìm x
x - 5 6 = 2 3
x × 2 3 = 7 3
23+x=78=456
x-56=78
x+56=56
Phần đầu mình không biết
x= 78-56
x= 22
x= 56-56
x=0
tk nha@@@@@@@@@@@@@@@@@@@
k cho minh di xong minh k lai cho bn nhanh thi dc nhe
a hihihihi
huhuhuuhu
aaaaa
uuuuuuuuuuuuuuuu
iiiiiiiiii
hhhhhhhhhhhhhhh
bbbbbbbbbbbbbbbbbbb
eeeeeeeeeeeeeeeeeee
wwwwwwwwwwwwwwwwwwww

Tìm x :
a./ x-15=53
b./43-x=23
c./ 23+x=56
a./ x-15=53
x=53+15
x=68
b./43-x=23
x=43-23
x=20
c./ 23+x=56
x=56-23
x=33
a) x - 15 = 53
=> x = 53 + 15
=> x = 68
b) 43 - x = 23
=> x = 43 - 23
=> x = 20
c) 23 + x = 56
=> x = 56 - 23
=> x = 33
56 - x = 23
23*56+56*23+56*54
BT: tìm x
1) 15- (- x - 3)= -38-22
2) -( x-23) + 18 = -x + (23 - x)
3) - (x-25)={ 48- [ 56 - (23 - 38 )] }
a, \(15-\left(x-3\right)=-38-22\)
\(15-\left(x-3\right)=-60\)
\(x-3=15-\left(-60\right)\)
\(x-3=75\)
\(x=78\)
56 - x = 23

mk ghét bn bn ko check mk mà lại check nó,rõ ràng mk nhanh hơn mà..............!!!!!!!!!!!
