Answer:
A=50
Step-by-step explanation:
5x10=50in
x − 3y = 12
<span>2x + 6y = 60</span>
<span>x=12+3y</span>
<span>2(12+3y)+6y=60</span>
<span>24+6y+6y=60</span>
<span>24+12y=60</span>
<span>12y=60-24</span>
<span>12y=36</span>
<span>y=36/12</span>
<span>y=3</span>
<span>and since the only answer you have with y being 3 is 21,3 the answer is D.(21,3)</span>
