Question

1)50*(x:16)=40150. 2)2700+y*400=170700. 3)(12300-30):k=30

Answer 1

50 * ( х / 16 ) = 40150
х / 16 = 40150 / 50
х / 16 = 803
х = 803 * 16
х = 12848

2700 + у * 400 = 1700
у * 400 = 1700 - 2700
у * 400 =  -1000 
у =  -1000 / 400
у =  -2,5

( 12300 - 30 ) / к - 30
12270 / к = 30
х = 12270 / 30
х = 409
