Question

1. the difference between two numbers is 9. the first number plus twice the other number is 27. find the two numbers. which 2 equations would help solve this equation?

□ x - y = 9
□ x + 2y = 27
□ 2x - y = 27
□ x + y = 9

Explanation:

Let the first number be \( x \) and the second number be \( y \). The difference between the two numbers is 9, so the equation is \( x - y = 9 \). The first number plus twice the other number is 27, so the equation is \( x + 2y = 27 \). The other equations do not match the given conditions.

Answer:

A. \( x - y = 9 \)
B. \( x + 2y = 27 \)
