Tìm \(\Large x\), biết: a) \(\Large x-1234=4040:4\) b) \(\Large 4532-x

Tìm \(\Large x\), biết:

a) \(\Large x-1234=4040:4\)                                 

b) \(\Large 4532-x=1123+1011\)

• A.

  a) \(\Large x\) =

  2244
• B.

  b) \(\Large x\) =

  2398

a) \(\Large x\) - 1234 = 4040 : 4

\(\Large x\) - 1234 = 1010

\(\Large x\) = 1234 + 1010

 \(\Large x\) = 2244

b) 4532 - \(\Large x\) = 1123 + 1011

4532 - \(\Large x\) = 2134

 \(\Large x\) = 4532 - 2134

 \(\Large x\) = 2398
