Thế nào là động vật quý hiếm

a) 2(x + 15) - 7 - x = 15 + 2x

2x + 30 - 7 - x = 15 + 2x

2x - x - 2x = 15 - 30 + 7

-x = -8

x = 8

b) - (x + 7) + 2(5 - x) = 4x + 15

-x - 7 + 10 - 2x = 4x + 15

0x = 19

Vậy phương trình vô nghiệm

x + 16=8x3

x+16=24

x=24-16

x=8

k mk nhé

x + 16 = 8 * 3 

x + 16 = 24

x = 24 - 16

x = 8
