Set up two equations.
s + 12 = l , s + l = 74     (these equations represent the problem)
 s + (s + 12) = 74           plug in "l" to the second equation.
2s + 12 = 74               combine like terms.
2s + 12 - 12 = 74 - 12     subtract to isolate the variable
2/2s = 62/2     divide to isolate the variable.
s = 31.       This means the smaller number is 31.
31 + 12 = 43.   since the larger number is 12 more than the smaller, add 12.
l = 43              the larger number has a value of 43.
small number = 31
larger number = 43
hope this helps! :D

Answer:
D) 57
Step-by-step explanation:
1/3x- 1/2 = 18 1/2
1/3x = 19
(3) * 1/3x = 19 (3)
x = 57
 
        
                    
             
        
        
        
Let the weight if a whole pizza be x grams
Then 1/4 of a pizza weighs x/4  grams and one eighth weighs x / 8.  The difference is 32 grams so we can make the following equation:-
x/4 - x/8  = 32
x / 8  = 32
Multiplying both sides by 8:-
x = 8*32 =  256 
Answer is 256 grams.
