Answer:
x = 1/2
Step-by-step explanation:
4x - 3 + 5 = 2x + 7 - 8x
4x + 2 = -6x + 7
10x + 2 = 7
10x = 5
x = 5/10
x = 1/2
 
        
             
        
        
        
Answer:
$108
Step-by-step explanation:
Let n be the cost of a keychain, then the cost of a T-Shirt would be 4n. We can use this to set up an equation...

Combine like terms
5n=135
Divide both sides by 5
n=27
Now we need to find how much she made from selling T-Shirts...
4n=4(27)=$108
