kick mik nha bạn
x+678=2813
=>x=2813-678
=>x=2135
4529+x=7685
=>x=7685-4529
=>x=3156
x + 678 = 2813 ; 4529 + x = 7685 ; x - 358 = 4768 ; 2495 - x = 698
x = 2813 - 678 x = 7685 - 4529 x = 4768 + 358 x = 2495 - 698
x = 2135 x = 3156 x = 5126 x = 1797
\(x\times23=3082\) ; \(36\times x=27612\) ; \(x:42=938\) ; \(4080:x=24\)
\(x=3082:23\) \(x=27612:36\) \(x=938\times938\) \(x=4080:24\)
\(x=134\) \(x=767\) \(x=879844\) \(x=170\)
Nếu sai thì sữa giùm mik nha
