The sum of two numbers is 74. If the larger number is subtracted from three times the smaller, the result is 42. Find the numbers.

Answer 1

x + y = 74
3y - x = 42

x = 74 - y

3y - 74 - y = 42
2y = 116
y = 58

Answer 2

a + b = 74 so b = 74-a

3a - b = 42

-------------------------------
3 a - 74 + a = 42

4 a = 116

etc

Answer 3

-74+y not -74-y I think
