a) 3x = 15
b) x + 6 = 10 - X
c) 12x = 24
d) 2x + 6 = 10
e) 7y + 8 - 2y = 24 - 2y + 5y
f) 4p = 3 + 6p - 12
c) 2x + 18+ 2 + 4x + 6x + 15 - 4x
h) 2 + 5 = 3 + 12

Answer 1

Explicación paso a paso:

a) 3x = 15

x= 15/3

x = 5

b) x + 6 = 10 - x

x + x = 10 - 6

2x = 4

x = 4/2

x = 2

c) 12x = 24

x = 24/12

x = 2

d) 2x + 6 = 10

2x = 10 - 6

2x = 4

x = 4/2

x = 2

e) 7y + 8 - 2y = 24 - 2y + 5y

7y - 2y + 2y - 5y = 24 - 8

2y = 16

y = 16/2

y = 8

f) 4p = 3 + 6p - 12

4p - 6p = 3 - 12

-2p = -9

p = -9 / -2

p = 4.5

g) 2x + 18 + 2 + 4x + 6x + 15 - 4x

2x + 18 + 2 + 4x + 6x + 15 - 4x = 0

2x + 4x + 6x - 4x = -18 - 2 - 15

8x = -35

x = -35/8

x = -4.375

h) 2 + 5 = 3 + 12

7 = 15 (F)
