Answer:
x = -3
Step-by-step explanation:
15 - 2x = -7x
add 2x 
15 = -5x
divide by -5
-3 = x
 
        
             
        
        
        
    6b + 6p = 33.60              ; b=2.90
6(2.90) + 6p = 33.60
17.40 + 6p = 33.60
-17.40           -17.40
    6p = 16.20
     /6         /6
      p = 2.70

Answer:
D
Step-by-step explanation:
Either try all the numbers and see which ones work or do the following.
Times both sides by 2x-5.
3=x(2x-5)=2x^2-5x
Rearrange and solve the quadratic. I will factorise.
2x^2-5x-3=0
(2x+1)(x-3)=0
so x = -1/2 or 3
