1. IF -(b+2)/3+2= -1, then b=?
   
   
2. If the ratio of x to y is 3/2 and the ratio of x to z is 7/4, what is the ratio of y to z?
   
   
3. If 4p +q= 13 and p-q=2, then pq=?
   
   
4. If a is 4 more than the quotient of b and 3, and if b=2, then what is the value of a?

Thank you for your help thomas

I will give you some help with question 4.

First you need to take the statement "a is 4 more than the quotient of b and 3" and write it as an equation.

• The quotient of b and 3 is ^b/₃.
  
  
• Four more than the quotient of b and 3 is  ^b/₃ + 4.
  
  
• Thus a =  ^b/₃ + 4

Next let b = 2 and thus a = ²/₃ + 4
