Question

(250:y-50)*80=600 решите ​

Answer 1

250:у-50=600:80

250:у=7,5+50

250:у=57,5

У=250:57,5

У=4 8\23

Answer 2

$(250 \div y - 50) \times 80 = 600$

$250 \div y - 50 = 600 \div 80$

$250 \div y - 50 = 7.5$

$250 \div y = 7.5 + 50$

$250 \div y = 57.5$

$y = 250 \div 57.5$

$y = \frac{100}{23}$

$y = 4 \frac{8}{23}$
