Question 722470: The sum of two integers is 10. Three times the larger integer is three less than eight times the smaller integer. Find the integer

x + y = 10 ----> x = 10 - y
3x = 8y - 3
Substitute x = 10-y into the second equation.
3(10 - y) = 8y - 3
30 - 3y = 8y - 3
-11y = -33
y = 3
solution: (x, y) = (7, 3)
