2x + y = 19

• (10,-1)

• (-1,10)

• (3,-4)

• (6,7)

Solve using elimination method.

x-y=11

2x+y=19

• (10,-1)

• (-1,10)

• (3,-4)

• (6,7)

Solve using Elimination Method:

x - y = 11

2x + y = 19

• (10,-1)

• (-1,10)

• (3,-4)

• (6,7)

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

4x + 3y = 1

x - 3y = -11

• cross out the 3y and -3y

• cross out the 4x and x

• change all the signs of the second equation

• add 1 and -11

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
