1) 115 - (35+y) = 39

2) 13+10t=163

3) 181-8r=45

4) 14 (p-30) = 630

5) 124: (y-5) = 31

1) 115 - (35+y) = 39

- (35+у) = 39-115

35+у=115-39

у=76-35

у=41

2) 13+10t=163

10t = 163-13

10t=150

t=150:10

t=15

3) 181-8r=45

-8r=45-181

-8r=-136

r=-136: (-8)

r = 17

4) 14 (p-30) = 630

p-30=630/14

p-30=45

p=75

5) 124: (у-5) = 31

у=124:31+5

у=9
