Elimination Method Different Coefficients

What would be the first step in finding the solution using elimination?

4x +  8y = 20

-4x + 2y = -30

When you solve these equations using the elimination method, which variable will be eliminated?

Look for ____ when determining which variable to eliminate. Select all that apply

To find the second variable, substitute the x or y you solved for into one of the ____.

Solve the following system of equations using the elimination method:

Solve the system with linear combinations method (Elimination method).

x + 4y = -4

3x + 5y = 2

Type in answer with no spaces between terms. Ex: (-2,1)

If no soultion type in NS

If infinitely many solutions type in IMS

Using elimination method, what would the correct next step be? Not interested in the answer.

what would the top equation become when you multiply everything by -1?

Solve:

x = -3y - 17

2x + 3y = -7

Solve the system with linear combinations method (Elimination method). x + 4y = -4 3x + 5y = 2 Type in answer with no spaces between terms. Ex: (-2,1) If no soultion type in NS If infinitely many solutions type in IMS
