Answer 2

Respuesta:

a. x + 29 = 86

x+29 = 86

x+29-29 = 86-29

x = 57

b. x + 35 = 78

x+35 = 78

x+35-35 = 78-35

x = 43

c. x − 28 = 91

x - 28 = 91

x-28+28 = 91+28

x = 119

d. x − 57 = 68

x-57 = 68

x-57-68 = 68-68

x-125 = 0

x = 125

e. 2. x = 1242

2x/2 = 1242/2

x = 621

f. 3. x = 2331

3x = 2331

3x/3 = 2331/3

x = 777

g. x/12 = 123

12(x/12) = 123(12)

x = 123(12)

x = 1476

h. x: 23 = 103

X/23 = 103

23(x/23) = 23(103)

x = 2369
