Two numbers have a sum of 303 and a difference of 63. find both numbers

Set up the following equations:




We'll use substitution to eliminate a variable. Because we already have the same positive and negative coefficient with the variable y, we can combine the equations:



Divide both sides by 2 to get x by itself.



Plug this value into one of the equations. We'll plug this value in the first equation:



Subtract 183 from both sides to get y by itself.



The two numbers are 120 and 183.
