Solve the system of equation
8x+4y=12
y=-2x+3

All real numbers if you graph these two lines they are on each line infinite many solutions

Step-by-step explanation:8X+4(-2X+3)=12

8X-8X+12=12

X cancels

12=12

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

Step-by-step 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.
