Question

Упростить выражение 1380:(37-x:26)=115

Answer 1

$1380 \div (37 - x \div 26) = 115 \\ 1380 \div (37 - \frac{1}{26} ) = 115 \\ 1380 \div \frac{962 - x}{26} = 115 \\ 1380 \times \frac{26}{962 - x} = 115 \\ \frac{35880}{962 - x} = 115 \\ 35880 = 115(962 - x) \\312 = 962 - x \\ x = 962 - 312 \\ x = 650$
