24*(z+9)=288
z+9=288-24
z+9=264
z=264-9
z=255
......................
(у+25)/8=16
у+25=8*16
у+25=128
у=128-25
у=103
............................
124/(у-5)=31
у-5=124/31
у-5=4
у=5+4
у=9
......................
38*х+15=91
38*х=91-15
38*х=76
х=76/38
х=2

44/z+9=20
44/z=20-9
44/z=11
z=44/11
z=4

Answer 2

X=56÷8=7
x=12+7=19
