Respuesta :

The answers are n = 49, x = 59 and y = 9.

Step-by-step explanation:

Keep the unknown terms on one side and constant terms on other side to solve the given expressions.

1) Solve 67=n +18

n = 18 - 67

n = 49

2) Solve x-16=43

x = 43 + 16

x = 59

3) Solve 54=6y

6y = 54

y = 54/6

y = 9
