Answer 1

Explicación paso a paso:

7.-

a) c + 4 = 53

c = 53 - 4 = 49

b) 3j = 48

j = 48/3 = 16

c) 4s = - 400

s = -400/4 = - 100

d) - 10y = 1400

y = 1400/-10 = - 140

e) 144 = 8c

144/8 = c = 18

f) - 2s = 0

s = 0/-2 = 0

g) 61 = x - 43

61 + 43 = x = 104

h) 12 + x = 31

x = 31 - 12 = 19

8.-

a) X - 31 = 28

X = 28 + 31 = 59

b) a + 4 =- 21

a = - 21 - 4 = - 25

c) 43 = m + 18

43 - 18 = m = 25

d) 21 = s - 40

21 + 40 = s = 61

e) 115 = u - 23

115 + 23 = u = 138

f) 42 + t = 0

t = 0 - 42 = - 42

g) 16 = 34 + v

16 - 34 = V = - 18

h) 100 - 2 = 23 + w

98 - 23 = w = 75

I) X + 2.3 = 50

X + 6 = 50

X = 50 - 6 = 44
