Two numbers have a sum of 108 and a difference of 44. Find the numbers.

I'm unsure how to start this problem.

Thank you
 


Start by picking variable names to represent these two unknown numbers that you've been asked to find.

For example, you could make the following choices.

x = the larger number

y = the smaller number

Now, use these symbols to write equations that model the given statements about their sum and difference.

Solve the resulting system of two equations.

Please show your work, if you want more help. 8-)
