Answer :

To solve the system of equations:

[tex]\[ \begin{cases} 6x - 2y = -2 \\ y = 3x + 12 \end{cases} \][/tex]

we can use the substitution method. Here are the detailed steps:

1. Substitute the value of [tex]\( y \)[/tex] from the second equation into the first equation:

[tex]\[ y = 3x + 12 \][/tex]

Substitute [tex]\( y \)[/tex] in the first equation:

[tex]\[ 6x - 2(3x + 12) = -2 \][/tex]

2. Simplify the equation:

Distribute the [tex]\( -2 \)[/tex]:

[tex]\[ 6x - 6x - 24 = -2 \][/tex]

Combine like terms:

[tex]\[ 0 - 24 = -2 \][/tex]

This simplifies to:

[tex]\[ -24 = -2 \][/tex]

3. Analyze the result:

The simplified equation [tex]\( -24 = -2 \)[/tex] is a contradiction; it is not true. This means that there is no solution that satisfies both equations simultaneously.

Therefore, the system of equations:

[tex]\[ \begin{cases} 6x - 2y = -2 \\ y = 3x + 12 \end{cases} \][/tex]

has no solutions. This indicates that the lines represented by these equations are parallel and do not intersect.
