Question

a) 14 + x = 2
b) 2x + x - 16 = 2
c) 8 - 17x = 25
d) 5 - x = 20 + 2x
e) x + 21 = 3 - 5x
f) 17x - 3 + x = 12 - 2x + 5
g) 2 (x - 12) = 210 - 7x
h) (5x - 1)2 - 2x - 3 = 35 - 3(2x + 4)​

Answer 1

Ответ:

a) 14 + x = 2

х = -12

b) 2x + x - 16 = 2

х = 6

c) 8 - 17x = 25

х = -1

d) 5 - x = 20 + 2x

х = -5

e) x + 21 = 3 - 5x

х = -3

f) 17x - 3 + x = 12 - 2x + 5

х = 1

g) 2 (x - 12) = 210 - 7x

х = 26

h) (5x - 1)2 - 2x - 3 = 35 - 3(2x + 4)

х = 2
