Which equation can be solved by using this system of equations?

[tex]
\[
\begin{cases}
y = 3x^3 - 7x^2 + 5 \\
y = 7x^4 + 2x
\end{cases}
\]

[/tex]

A. [tex]3x^3 - 7x^2 + 5 = 0[/tex]

B. [tex]3x^3 - 7x^2 + 5 = 7x^4 + 2x[/tex]

C. [tex]7x^4 + 2x = 0[/tex]

D. [tex]7x^4 + 3x^3 - 7x^2 + 2x + 5 = 0[/tex]

Answer :

To solve this problem, we're given a system of equations:

1. [tex]\( y = 3x^3 - 7x^2 + 5 \)[/tex]
2. [tex]\( y = 7x^4 + 2x \)[/tex]

We need to determine which of the listed equations can be solved using this system of equations. Here's how we can approach this:

### Step 1: Setting the Equations Equal to Each Other

Since both equations are set equal to [tex]\( y \)[/tex], we can equate them:

[tex]\[ 3x^3 - 7x^2 + 5 = 7x^4 + 2x \][/tex]

This equation is clearly one of the choices given:
[tex]\[ 3x^3 - 7x^2 + 5 = 7x^4 + 2x \][/tex]

### Step 2: Individual Equations

Next, consider each equation individually:

- From the first equation: [tex]\( y = 3x^3 - 7x^2 + 5 \)[/tex], we can set this equal to zero:
[tex]\[ 3x^3 - 7x^2 + 5 = 0 \][/tex]

- From the second equation: [tex]\( y = 7x^4 + 2x \)[/tex], we can also set this equal to zero:
[tex]\[ 7x^4 + 2x = 0 \][/tex]

Both of these are options as well and correspond to two other choices given:
- [tex]\( 3x^3 - 7x^2 + 5 = 0 \)[/tex]
- [tex]\( 7x^4 + 2x = 0 \)[/tex]

### Step 3: Combined Polynomial Coefficients

Lastly, let's analyze if there could be a combination or error in initially given equations:

The equation [tex]\( 7x^4 + 3x^3 - 7x^2 + 2x + 5 = 0 \)[/tex] seems to be a combination of terms from both [tex]\( y \)[/tex] equations. However, it doesn't directly result from the step-by-step process derived from setting [tex]\( y \)[/tex]-components to zero or each other.

### Conclusion

The possible equations that can result from manipulating the given system of equations are:

- [tex]\( 3x^3 - 7x^2 + 5 = 7x^4 + 2x \)[/tex]
- [tex]\( 3x^3 - 7x^2 + 5 = 0 \)[/tex]
- [tex]\( 7x^4 + 2x = 0 \)[/tex]

Thus, these correspond to the first three choices and can be solved using the system provided.
