Answer:

28. x = 3 31. x = -3

Step-by-step explanation:

x = 3

x/-3 = 1

multiply both sides by -3

x/-3 (-3) = 1 (-3)

harkovskaia [24]

Answer:

C. x=-2

Step-by-step explanation:

To solve use PEMDAS,

Add x to both sides

6=16+5x

Subtract 16 from both sides

-10=5x

Divide both sides by 5

2^3y+6 = 2^4/2^(4y)

2^(3y+6) = 2^(4-4y)

3y + 6 = 4 - 4y

7y = -2

y = -2/7
