<u>5x^3-20x+10x</u>
For these polynomial multiplication problems, just distribute the number outside the parentheses.

Answer:
- A Subtract the bottom equation from the top equation.
- B Add the equations.
Step-by-step explanation:
The x-terms are the same in each equation, so subtracting one equation from the other will eliminate the x-variable.
The y-terms are opposites in the two equations, so adding the two equations will eliminate the y-variable.
Both strategies (subtracting, adding) are applicable to this system of equations.
