Need help with this and its systems of linear equations and inequalities. It says: The sum of two numbers is 4. The lager number is 12 more than three times the smaller number. What are the numbers? And sadly its a word problem w/out answer choices.

swinn:

x + y = 4 y = 3x + 12 Substitute: x + 3x + 12 = 4 4x = -8 x = -2 y = 6
