Answer 1

a) a + 5 = -7

a = -7 - 5

a = -12

b) x - 2 = -10

x = -10 + 2

x = -8

c) a + 5 = -7

a = -7 - 5

a = -12

d) y - c = +8

10 - 2 = 8

e) 2x = -8

x = -8/2

x = -4

f) p/3 = -4

p = -4 . 3

p = -12

g) b + 35 = 69

b = 69 - 35

b = 34

h) x + 47 = 55

x = 55 - 47

x = 8

i) 2x = 24

x = 24/2

x = 12

j) 24 + p = 56

p = 56 - 24

p = 32
