WILL MARK BRAINLIEST Select the best possible first step to solving the system by first eliminating the x variable.

3x + 5y = 1
2x + 4y = −4

A. Multiply the first equation by 2, and multiply the second equation by 3.

B. Multiply the first equation by −2, and multiply the second equation by 3.

C. Multiply the first equation by −2, and multiply the second equation by −3.

D. None of the above

The possible answers here are so weird. When i did this i used a calculator to helped me and when tried using those answers and steps i needed getting really different answers from the calculator.

So I would think it is d. Non of the above

ps the correct answer would be add -4y and -5y to both sides

Step-by-step explanation:

hope this helps

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
