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.
