Question

Б)13у+15у-24=60,е)528:к-25=64 к)5905-27u=316

Answer 1

б)
13у+15у-24=60,
28у=60+24,
28у=84
у=84:28
у=3


е)528:к-25=64
528:к=64 +25
528:к=89
к=528:89
к=5 83/89

к)5905-27u=316
27u=5905-316
27u=5589
u=5589:27
u=207

Answer 2

б) 13у+15у-24 = 60
28y = 60+24
28y = 84
y = 84:28
y = 3

е) 528:k-25 = 64
528:k = 64+25
528:k = 89
k = 528:89
k = 5⁸³/₈₉

к) 5905-27u = 316
-27u = 316-5905
-27u = -5589
27u = 5589
u = 207
