Tìm \(\large x\), biết:

• A. \(\large x\) = 4783
• B. \(\large x\) = 4873
• C. \(\large x\) = 4387
• D. \(\large x\) = 4837

\(\large 12 965 \times 3 - x \times 7 = 21 656 : 4\)

\(\large 38 895 - x \times 7 = 5414\)

\(\large x \times 7 = 38 895 - 5414\)

\(\large x \times 7 = 33 481\)

\(\large x = 33 481 : 7\)

\(\large x = 4783\)
