Solve the system.

[tex]\[
\begin{aligned}
2x + y & = -3 \\
-2y & = 6 + 4x
\end{aligned}
\][/tex]

Write each equation in slope-intercept form.

[tex]\[
\begin{array}{l}
y = \square x + \square \\
y = \square + \square
\end{array}
\][/tex]

[tex]\( y = \)[/tex]



Answer :

Sure, let's solve the given system of equations step-by-step.

The system of equations is:

[tex]\[ \begin{aligned} 2x + y &= -3 \\ -2y &= 6 + 4x \end{aligned} \][/tex]

First, let's transform each equation into slope-intercept form, which is [tex]\( y = mx + b \)[/tex], where [tex]\( m \)[/tex] is the slope and [tex]\( b \)[/tex] is the y-intercept.

### Transforming the First Equation

The first equation is already quite close to the slope-intercept form:

[tex]\[ 2x + y = -3 \][/tex]

To isolate [tex]\( y \)[/tex]:

[tex]\[ y = -2x - 3 \][/tex]

### Transforming the Second Equation

The second equation is:

[tex]\[ -2y = 6 + 4x \][/tex]

First, solve for [tex]\( y \)[/tex] by dividing everything by [tex]\(-2\)[/tex]:

[tex]\[ y = \frac{6 + 4x}{-2} \][/tex]

Distribute the division on the right-hand side:

[tex]\[ y = -2x - 3 \][/tex]

### Final Slope-Intercept Form of Each Equation

So, the slope-intercept form for each equation is:

[tex]\[ \begin{array}{l} y = -2x - 3 \\ y = -2x - 3 \end{array} \][/tex]

### Conclusion

Both equations are exactly the same. This means that rather than describing two lines that intersect at a point, these equations describe the same line.

Thus, the system of equations is actually dependent, meaning that any point [tex]\((x, y)\)[/tex] on the line [tex]\(y = -2x - 3\)[/tex] is a solution to the system.

So, the solution to the system is the set of all points [tex]\((x, y)\)[/tex] that satisfy the equation:

[tex]\[ y = -2x - 3 \][/tex]
