The sum of two numbers is 67. The larger number is 4 more than 2 times the smaller. What are the two numbers?

Question

anonymous · Answer

x = larger number, y = smaller numer

x + y =67
2y + 4 = x
If you substitute you can solve  for both x and y

anonymous · Answer

2y + 4 + y = 67
3y + 4 = 67
minus 4 on both sides
3y = 63
divide by 3 on both sides
y = 21
Substitute "y" back in the original equation (x + y =67)
x + 21 = 67
minus 21 on both sides
x = 46

46 is 4 more than 2 times the smaller number 21, and 46 + 21 = 67.
