Answer 1

To solve this system using the addition method, you would need to multiply the first equation by what number in order for the x's to add out?



2x+3y=8



-6x+4y=11



A. 3

B. -3

C. 6

D. None of the above​

Multiply the first equation by 3

so

answer is option A

Verify

3*{2x+3y=8} ------> 6x+9y=24

adds equation 2

6x+9y=24

-6x+4y=11

---------------

the variable x is removed
