x=-44
k nhé mk vừa k bn rùi
x + 45 = 45 - 45 + 55 : 55
x + 45 = 45 - 45 + 1
x + 45 = 0 + 1
x + 45 = 1
x = 1 - 45
x = -44
x + 45 = 45 - 45 + 55 : 55
x + 45 = 45 - 45 + 1
x + 45 = 0 + 1
x + 45 = 1
x = 1 - 45
x = -44
x+45=45-45+55:55
x+45=1
x=1-45
x=-44
vậy x=44
x + 45 = 45 - 45 + 55 : 55
x + 45 = 0 + 1
x + 45 = 1
x = 1 - 45
x = - 44
tk nha Uchiha Sasuke !!!!!!!!!!!!!!!!!!!
x+45=45-45+55:55
x+45=45-45+1
x+45=0+1
x+45=1
x=1+45
x=46
Vậy x=46 Đúng 100%luôn
x+45=45-45+55+55
x+45=45-45+1
x+45=0+1
x+45=1
x=1-45
x=-44
=>x=-44
x + 45 = 45 - 45 + 55 : 55
x + 45 = 0 + 1
x + 45 = 1
x = 1 - 45
x= -44
