Question

a)2x=-7

b)3x+2=2x-11

 c)2x=16

d)x/2=-5

e)2x+14=5x-11

Answer 1

a ) 

$2x=-7\\x= \frac{-7}{2}$

B ) 

$3x+2=2x-11\\3x-2x=-11-2\\x=-13$

C )

$2x=16\\x= \frac{16}{2} \\x=8$

D )

$\frac{x}{2} =-5\\x=-10$

E )

$2x+14=5x-11\\2x-5x=-11-14\\-3x=-25~.(-1)\\3x=25\\x= \frac{25}{3}$

Answer 2

a)2x=-7
x= -7/2 ou -3,5

b)3x+2=2x-11
3x -2x = -11 -2
x= -13

c)2x=16
x= 16/2
x= 8

d)x/2=-5
x= 2.(-5) 
x= -10

e)2x+14=5x-11
2x -5x = -11 -14
-3x = -25.(-1)
3x = +25
x= 25/3
