Answer:
43, 31
Explanation:
Pick two numbers for variables, like a and b. 
Let a be the greater number. 
The largest of two numbers is 12 more than the smaller number translates to (the word "is" means equals sign) 
a = 12 + b 
They told you the sum of the two numbers is 74, and that translates to (sum means to add) 
a + b = 74. 
Now, solve for b, so you get 
b = 74 - a. 
Plug this back into the first equation of a = 12 + b and you get 
a = 12 + (74 - a) 
Now, solve for a 
a = 86 - a 
2a = 86 
a - 43 
Now, you need to answer the question asked and find b. Well, look at your two original equations 
a + b = 74 
43 + b = 74 
b = 31
