the larger of two numbers is nine less than four times the smaller number. If the sum od the two numbers is 76, find both numbers

x = larger number
y = smaller number

x = 4y - 9
x + y = 76

4y - 9 + y = 76
5y = 76 + 9
5y = 85
y = 85/5
y = 17

x + y = 76
x + 17 = 76
x = 76 - 17
x = 59

ur numbers are 17 and 59
