Answer:
Step-by-step explanation:
a) set up the variables 
Let x represent the first number Then  y will represent the second number. 
b) What is the equation that represents the above situation? 
c) Solve the equation.
<u>Substitute x in the second equation and solve for y:</u>
- x + y = 51
- 2y + y = 51
- 3y = 51
- y = 51/3
- y = 17
<u>Then find x</u>
