1. 14b= - 42   

b= -42/14

b= -3

 2. - 8k = 56  

k= 56/-8

k= -7

3.- T= - 13  

T= 13

4. 2/3 M = 14  

M= 14*3/2

M= 21

5. b/7 = - 3 

b= -3*7

b= -21

 6. - 2.8 = - 0.7T  

-2.8/-0.7 = T

T= 4

 7. - U/2 = -15 

-U= -15*2

-U= -30

 8. 6 = - 18w

6/-18=w

-1/3=w

9. 1.3x = 5.33   

X= 5.33/1.3

X= 

10. 5/4 k= - 1/2   

k= -1/2*4/5

k = -4/10

k= -2/5

11. - 9/4 x = - 3/5  

X= -3/5*-4/9

X= 12/45

X= 4/15

12. 100= 5k 

100/5= k

K= 20

 13. 31= -p 

p = -31

14. 3p = 5/2 

p = 5/2*1/3

p = 5/6

 15.-4a = 0

a= 0/-4

a= 0
