Answer :
To determine which equation can be solved using the given system of equations, let's look closely at the system:
1. First equation: [tex]\( y = 3x^3 - 7x^2 + 5 \)[/tex]
2. Second equation: [tex]\( y = 7x^4 + 2x \)[/tex]
Since both equations equal [tex]\( y \)[/tex], we can set these two expressions equal to each other to find a relationship between them. This leads to the equation:
[tex]\[ 3x^3 - 7x^2 + 5 = 7x^4 + 2x \][/tex]
This equation matches one of the options provided:
- [tex]\( 3 x^3-7 x^2+5=0 \)[/tex]
- [tex]\( 3 x^3-7 x^2+5=7 x^4+2 x \)[/tex]
- [tex]\( 7 x^4+2 x=0 \)[/tex]
- [tex]\( 7 x^4+3 x^3-7 x^2+2 x+5=0 \)[/tex]
The equation [tex]\( 3x^3 - 7x^2 + 5 = 7x^4 + 2x \)[/tex] corresponds to the second option. This is the equation derived directly from equating the two given functions, meaning it can indeed be solved using the system of equations.
