( 2746 - x ) - 258 = 1360
25 × x - x = 14040 : 45
x : 1/2 + x : 1/7 + x : 1/3 = 864
( 5915 + 3550 : 25 ) - 76 × 25
7 × 2/3 - 2/5 : 1/2 - 2/3
1\(\frac{2}{3}\): \(\frac{2}{3}\)- \(\frac{3}{4}\)× \(\frac{2}{3}\)+ 5\(\frac{3}{7}\)
1\(\frac{1}{3}\)+ 1\(\frac{1}{4}\): 1 \(\frac{1}{2}\)+ 2\(\frac{3}{4}\)× 2\(\frac{2}{3}\)
\(\left(2746-x\right)-258=1360\)
\(2746-x=1360+258\)
\(2746-x=1618\)
\(x=2746-1618\Rightarrow x=1128\)
