Step-by-step explanation:

Step 1:  Solve the first part

A: 66 + k + 10

B:  y^2

C: s + 49

D:  58 +c + 100

E: 62 * x

F: 29 - v

G:  7 / k  

H: w + 3

I: t * 45

J:  c * 3

K:  9 + w

L:  93 / y

Step 2:  Solve the second part

A:  (3.6 * t) + (3.6 * 4.6) = 4

    3.6t + 16.56 - 16.56 = 4 - 16.56

    3.6t / 3.6 = -12.56 / 3.6

    t = -3.4888...

 

B: 2.6 = (6 * c) + (6 * -3.7)

     2.6 + 22.2 = 6c - 22.2 + 22.2

     24.8 / 6 = 6c / 6

     4.1333... = c

 

C: (4 * -1.8) + (4 * -p) = -2.4

    -7.2 - 4p + 7.2 = -2.4 + 7.2

    -4p / -4 = 4.8 / -4

     p = -1.2

 

D: (8 * z) + (8 * -3.1) + 6 = 3z + 5

       8z - 24.8 + 6 - 3z = 3z + 5 - 3z

5z - 18.8 + 18.8 = 5 + 18.8

5z / 5 = 23.8 / 5

z = 4.76
