Answer:
The steps will be :
1. Draw both equations into the graph.
2. Look for the coordinates where they intersect(curve and line crosses each other). So the coordinates will be (-2,0) and (3,5).
3. The x-value of the coordinates will the solution to the equations.
4. Therefore, the answer will be -2 and 3.
Since triangle ADE is similar to triangle ABC and the scale factor is 2, the following relation must be fulfilled:

The, by substituting the given information, we have

By multiplying both sides by x+2, we get

which gives

Then, by subtracting 4x to both sides, we have

and by adding 8 to both sides, we obtain

then, x is given by

Then, by substitutn
From the second we can find:
y=7x-23
Now using this value of y in the first equation you have:
14x-2(7x-23)=46
14x-14x-46=46 which is always true meaning that there are infinitely many solutions.
Basically both equations describe the same line so every point on the line is a solution...
