Answer: 
Step-by-step explanation:
1. Substitute 
into first equation and solve for "x" in order to find the x-intercept of the first line:
2. Substitute 
into the first equation and solve for "y" in order to find the y-intercept of the first line:
Knowing that first line passes through the points 
and 
, you can graph it.
3. Substitute into second equation and solve for "x" in order to find the x-intercept:
4. Substitute into the second equation and solve for "y" in order to find the y-intercept of the second line:
Knowing that second line passes through the points 
and 
, you can graph it.
The solution of the system of equations is the point of intersection between the lines. Therefore, the solution of this system is:
y+2=-3x+12
-2 -2
y=-3x+10
This is as far as it can be simplified.

Answer:
look at the picture i sent
Hopefully I’m not too late, but here’s how I solved it. Basically, replace F with 68. Subtract 32 from both sides so your equation becomes 9/5C=36. Divide both sides by 9/5 so C is left but itself (C=36/1.8). The answer should come out to 20. If you want to check my answer, plug 20 into the equation. Multiply 20x9/5 which equals 36. Add 36 and 32 together to get 68. Hope this helps
