Question

Which of these strategies would eliminate a variable in the system of equations?

23 - 5y = 13
- 3x + 2y = 13

Choose all answers that apply:

A. Subtract the bottom equation from the top equation.

B. Multiply the top equation by 3. multiply the bottom equation by 2. then add the equations.

C. Multiply the top equation by 2, multiply the bottom equation by 3, then add the equations

Answer 1

Answer: Multiply the top equation by , multiply 3 the bottom equation by 2, then add the equations.

Explanation:

6x - 15y = 39

+ (- 6x + 4y) + (26)

- 11y = 65
