One number is 11 more than 3 times another number. their sum is 75. find the smaller number.

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
