x-26754=43267
x =43267+26754
x =70021.
x+456=789
x = 789-456
x =333.
a) x = 43267 - 26754 = 16513
b) x = 789 - 456 = 333
x - 26754 = 43267
x = 43267 + 26754
x = 70021
x + 456 = 789
x = 789 - 456
x = 333
\(x-26754=43267\)
\(x\) \(=\)\(43267+26754\)
\(x\) \(=\)\(70021\)
\(x+456=789\)
\(x\) \(=789-456\)
\(x\) \(=\)\(333\)
a,X - 26754 = 43267
X = 43267 + 26754
X = 70021
b,X + 456 = 789
X = 789 - 456
X = 333
a, x-26754=43267
x=43267+26754
x=70021
Vậy x=70021
b, x+456=789
x=789-456
x=333
Vậy x=333
x-26754=43267
x=43267+26754
x=70021
