which of these strategies would eliminate a variable in the system of equations - 7x+2y=5 and 3x-5y=-5

Step-by-step explanation:

hello:

-7x+2y=5 ... (*)

3x-5y=-5 ... (**)

these strategies:

1) multiply (*) by : 5

2) multiply (*) by : 2

3) add the equations

Multiply the top eq by3, Multiply the bottom eq by 7 then add the eq,

Multiply the top eq by 5 multiply the bottom eq by 2 then add the eq

Step-by-step explanation:

Add the top and the top and bottom eq and pit them together
