The sum of two numbers is 20. The larger number is four less than twice the smaller number. What are the two numbers? Choose the correct choice from the following answers.
A) 7 and 12	B) 8 and 12	C) 9 and 12	D) 10 and 12	E) None of these
Let x and y be the two numbers such that x is larger than y. The statement "the larger number is four less than twice the smaller number" may be formulated by   x = 2y - 4   We use the sum of the two numbers to write a second equation.   x + y = 20   Substitute x by 2y - 4 in x + y = 20 to obtain   2y - 4 + y = 20   Solve for y to find   y = 8 and x = 2y - 4 = 12   Answer 8 and 12
