Answer 1

Explicación paso a paso:

a) x + 9 = 25

x = 25 - 9 = 16

b) 8x = 24

x = 24/8 =  3

c) x/4 = 37

x = 37 * 4 = 148

d) x - 4 = 47

x = 47 + 4 = 51

e) x² =36

x = √36 = 6

f) √x = 2

x = 2² = 4

g) 2x + 7 = 11

2x = 11 - 7

x = 4/2 = 2

h) x/10 + 2 = 30

x/10 = 30 - 2

x = 28 * 10 = 280

i) 3x - 5 = 31

3x = 31 + 5

x = 36/3 = 12

k) x² + 5 = 21

x² = 21 - 5

x = √16 = 4

l) √x - 1 = 9

√x = 9 + 1

x = 10² = 100
