Answer:
x = -3
In-Depth Steps:
1.) Start with the bottom equation: 
2.) Set 
alone on one side of the equal sign. Your equation will look like 
.
3.) Plug 
in for in the first equation. You will get 
.
4.) Distribute. Your equation now looks like this: 
.
5.) Combine like terms. You will get 
.
6.) Subtract 6 from both sides. You get 
. We can learn that Y=0.
7.) Go back to either equation and put 0 in for y.
8.) In the top equation, it would look like 
and the bottom equation would look like 
. We basically got our answer of 
, but we will plug it into the equation, and in-fact, we get x = -3.
Hi there
One pound of salmon will cost $13, and one pound of tuna will cost $8.
Here's why.
X will be the cost of pound of salmon, and y will be the cost of a pound of tuna.
| 15x+8y=259
| 12x+6y-204
6y = 204-12x
y=34-2x
15x+8(34-2x)=259
272-259=16x-15x
x=13
y=34-2*13
y=34-26
y=8
So, again...
1lb Salmon : $13
1lb Tuna : $8
If O is the orthocenter, O=(xo, yo)
such that xo=(2+0 + 2)/3, so xo= 4/3, so the answer must be

9 4/21
Hope this helps, i apologize if i’m incorrect
