​x₂+2x₄​+3x₅​=0
4x₄+8x₅=0​

Answer 1

To solve a system with both linear and quadratic equations, use substitution or elimination for the linear part and the quadratic formula for the quadratic equation.

Step-by-step explanation:

The question presented involves solving systems of equations and quadratic equations which are topics in mathematics, typically covered at the high school level.

To solve a system that includes a quadratic equation, you can often use substitution or elimination methods for linear equations and the quadratic formula for the quadratic ones. Let's walk through the steps typically taken:

1. Solve linear equations for one variable in terms of the others.
2. Substitute the expressions obtained into any quadratic equations.
3. Use the quadratic formula: x = (-b ± √(b² - 4ac))/(2a), where the equation takes the form ax² + bx + c = 0.
