alguien me puede ayudar a) 9x = - 7 x + 32 g)7x - 2 =5 - x h) 11 + 8x = 2 -3x b) 4x = 2x + 3 i) 6 - 3x = -x + 1 j) -3x + 5 -x - 1 c) 6x - 5 = 7 k) 4x + 8 = 20 + 2x n) 4x + 1 = x + 4 d) 4x = -2x +18 m) 6x - 5 = 2x +7 p) x + 3 = 3x - 6 f) 3x = -2 +25 o) 5x + 1 = 4x + 5

Answer 1

Explicación paso a paso:

a) 9x = - 7 x + 32

16x = 32

x = 2

b) 4x = 2x + 3

2x = 3

x = 3/2

c) 6x - 5 = 7

6x = 12

x = 2

d) 4x = -2x +18

6x = 18

x = 3

f) 3x = -2 +25

3x = 23

x = 23 /3

g)7x - 2 =5 - x

8x = 7

x = 7 / 8

h) 11 + 8x = 2 -3x

11x = - 9

x = -9 / 11

i) 6 - 3x = -x + 1

5 = 2x

x = 2 / 5

j) -3x + 5 = -x - 1

6 = 2x

3 = x

k) 4x + 8 = 20 + 2x

2x = 12

x = 6

n) 4x + 1 = x + 4

3x = 3

x = 1

m) 6x - 5 = 2x +7

4x = 12

x = 3

p) x + 3 = 3x - 6

9 = 2x

9 / 2 = x

o) 5x + 1 = 4x + 5

x = 4
