Given:
The given two equations are
and
![8x+4y=12](https://img.qammunity.org/2021/formulas/mathematics/college/5en6vviwwsrucb1ggtfz9elho2k4j2xu1e.png)
We need to determine the solutions of the system of equations.
Solution:
Let us use the substitution method to determine the solution of the given system of equations.
Hence, substituting
in the equation
![8x+4y=12](https://img.qammunity.org/2021/formulas/mathematics/college/5en6vviwwsrucb1ggtfz9elho2k4j2xu1e.png)
Thus, we have;
![8x+4(-2x+3)=12](https://img.qammunity.org/2021/formulas/mathematics/college/ch16kv0xj5im7frj4g639yrx0ugvrbmg3p.png)
![8x-8x+12=12](https://img.qammunity.org/2021/formulas/mathematics/college/56loln0iwz2ebcoka9e9l03kvguwa2p270.png)
![12=12](https://img.qammunity.org/2021/formulas/mathematics/high-school/yk49zqigx4j5equmysol4pojhwane2qljm.png)
Since, both sides of the equation are the same, then the system of equations have infinitely many solutions.
Hence, Option 3 is the correct answer.
