1. 1 + p =0  

minus 1 over 

p=-1

2. -34 + t = -40 

add 34 to the other side

t=-6

3.  2/3= - 1.1 + m 

add 1.1 to 2/3 

2.1=m

 4. 7/11 = z + 3/11

minus 3/11 to the other side

4/11=z

 5. -2.5 = -1.1 + m   

add 1.1 to the other side

-1.4=m

6. w - 23 = -11

add 23 to the other side

w=12

7. p - 10 = - 9  

add 10 to the other side 

p=1

 8.  x + 21 = 16 

minus 21 to the other side

x=-5

9.  -2 = - 15   

add 2 to the other side 

=-13

10.  4.01 + p = 3.22 

minus 4.01 to the other side 

p=-0.79 

11.  T+ 3/8 = 2  

minus 3/8 to the other side 

t=1.625

12.  27 = z -22 

add 22 to the other side

 z=49

13.  -70 = -55 + w

add 55 to the other side 

w= -15
