Answer:

The answer to your question is they are the same equation. All real numbers.

Explanation:

Data

8x + 4y = 12 Equation l

y = -2x + 3 Equation ll

Process

1.- Solve the system of equations by substitution. Substitute equation ll in equation l,

8x + 4(-2x + 3) = 12

2.- Expand

8x - 8x + 12 = 12

3.- Solve for x

8x - 8x = 12 - 12

0 = 0

4.- Conclusion

As the result was 0 = 0 that means that both equations are the same, the the solution is all the points of the lines.
