First, multiply the second equation by 4 so that 8y can cancel out. Now you have
5x+8y=-29
and
28x-8y=-268
Add these equations to get
33x=-297
Divide both sides by 33, and you have
x=-9
Now, simply solve for y by plugging it into an equation, and you have
y=2
The final answer is (-9,2)!
Answer:
If n > 0, then n= 1
If n < 0, then n=n
If you could word this a bit differently, I might be able to help more, but this is what I'm getting from it. The way you worded it is a bit confusing.
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>
