<span>solve the equation ax – c = bx + d for x:
1) Group the x terms together on the left:     ax - bx - c = d
2) Group the constant terms together:          ax - bx = c + d
3) factor out x:                                             x(a - b) = c + d
4) Divide both sides of the equation by (a - b) to obtain a formula for x:
                                                       c+d
</span>           x(a - b) = c + d   =>    x = ---------
                                                       a-b
This shows that the given equation CAN be solved for x, but there is a restriction:  a must NOT equal b, because if a-b = 0, we'd have division by zero (which is not defined).
Where is Victoria's solution?  Please share it if you want to discuss this problem further.  Thank you.
        
                    
             
        
        
        
First find out how many Carly sold:-
90 ÷ 2 = 45
Carly sold 45 rolls
Add to find out how many the sold together:-
90 + 45 = 135
Jasmine and Carly sold 135 rolls of wrapping paper together. 
        
                    
             
        
        
        
Answer:
a) 7 members,
b) 3.
c)  4.
Step-by-step explanation:
I hope the following will help you understand what this diagram means:-
The 4 people in the area overlapped by the Music and Spanish areas are the people who are in both clubs. 
Obaid and Abdulraheem are in the Music Club only.
The number of members in the Music Club is these 2 plus the 4 in the overlap area, so there are 6 members in the Music Club.
 
        
             
        
        
        
Answer:
x=48
Step-by-step explanation:
(x+34)+(2x+2)=180
 
        
                    
             
        
        
        
1342:215 is the ratio take the first number you get and put it over the 215. Ratios are often expressed as fractions, so 1342/215 would be correct as well.
