Answer:
the sum of two numbers is 27. their difference is 5. find the number
Step-by-step explanation:
Let x be the first number and y be the second number    ...   so we have
x + y  = 27
x - y  =   5            Adding the equations, we have
2x = 32                Dividing through by 2, we have
x = 16                  And substituting  or x in the first equation, we have
16 + y  = 27         Subtract 16 from both sides  
y = 11
