So for this our goal is to isolate t since its the total price. All you have to do is add yz on both sides of the equation, and your answer should be 
X = larger number, y = smaller number
x + y = 75
x = 3y + 11
3y + 11 + y = 75
4y + 11 = 75
4y = 75 - 11
4y = 64
y = 64/4
y = 16 <=== ur smaller number
x = 3y + 11
x = 3(16) + 11
x = 48 + 11
x = 59...ur larger number
