1. 4 + x = - 2   

x=-2-4

x= -6

2. 4y = - 12 

y= -12/4

y= -3

  3. q - 4 = - 12   

q= -12+4

q=-8

4. h/4 = - 12  

h=-12*4

h= -48

5.  2/3 + T = 1  

T=1-2/3

T= 3/3-2/3

T= 1/4

6. 3/4 + q = 1  

q= 1-3/4

q= 4/4-3/4

q= 1/4

7. -9a = - 12

a = -12/-9

a= 4/3

8. 7= R - 23    

-R= -23-7

-R= -30

R= 30

9. - y/3 =5 

-y= 5*3

-y= 15

y= -15

10. 2p = 5/6  

p = 5/6*1/2

p= 5/12

11. - 7/3x = 9/10  

-x= 9*3/10*7

-x = 27/70

x = -27/70

12. t - 12.9 =15   

t= 15+12.9

t= 27.9

13. 5 + u = 3.2  

u= 3.2-5

u= -1.8

14. 2(1/2 -2y = 3/2)

2*1/2-2y*2= 3/2*2

1-4y= 3

-4y= 3-1

-4y= 2

-y = 2/4

-y = 1/2

y= -1/2
