Question

The sum of two numbers is 85. The second number is 4 more than 2 times the first number. Let x represent the first number and let y represent the second number. What are the two numbers? Use the table to guess and check.

Answer 1

Step-by-step explanation:

x+y=85

y=4+2x

$x = 85 - y \\ y = 4 + 2(85 - y) \\ y = 4 + 170 - 2y \\ 3y = 174 \\ y = 58 \\ x = 85 - y \\ x = 27$
