Answer:

x= -7

Step-by-step explanation:

-3x - 5 = 16

add 5 to both sides

-3x = 21

divide by -3 on both sides

x = -7

Answer:

x= -7

Step-by-step explanation:

-3x-5=16

add 5 on both sides to cancel out -5 on the left side

-3x -5+5=16+5

-5+5 cancels out which equals 0 and 16+5=21 resulting in:

-3x=21

divide both sides by -3 to cancel out -3x

-3x/-3=21/-3

resulting in your answer

x=-7
