Question

( 27 + x ) :2 + 10 = 380 + 200x 5

 

Answer 1

\(\left(27+x\right):2+10=380+200\times5\)

\(\left(27+x\right):2+10=380+1000\)

\(\left(27+x\right):2+10=1380\)

\(\left(27+x\right):2=1380-10\)

\(\left(27+x\right):2=1370\)

\(27+x=1370\times2\)

\(27+x=2740\)

\(x=2740-27\)

\(x=2713\)

Answer 2

`#3107.101107`

\(( 27 + x ) \div 2 + 10 = 380 + 200\times 5\\ (27 +x) \div 2 + 10 = 380 + 1000 \\ (27 + x) \div 2 + 10 = 1380 \\(27 + x) \div 2= 1380 - 10 \\ (27 + x) \div 2 = 1370 \\ 27 + x = 1370\times 2 \\ 27 + x = 2740 \\ x = 2740 - 27 \\ x = 2713 \)

Vậy, `x = 2713.`

Answer 3

\((27+x):2+10=380+200\times5\\(27+x):2+10=380+1000\\(27+x):2+10=1380\\(27+x):2=1380-10\\(27+x):2=1370\\27+x=1370\times2\\27+x=2740\\x=2740-27\\x=2713\\Đáp.số:x=2713\)
