Can someone me with this and make the answer right and you
given the following system of equations:

2x + 6y = 12
4x + 3y = 15

which action creates an equivalent system that will eliminate one variable when they are combined?

multiply the second equation by −2 to get −8x − 6y = −30.
multiply the first equation by 2 to get 4x + 12y = 24.
multiply the second equation by −4 to get −16x − 12y = −60.
multiply the first equation by −4 to get −8x − 24y = −48.

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
