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

Answer explanation

Solve using Elimination Method:

x - y = 12

4x + y = 33

• (-9,-3)

• (3,-9)

• (9,-3)

• (-3,9)

Answer explanation

Solve the system:

x + 6y = 17

-x + 3y = -8

• (5, 2)

• (11, 1)

• (1, 11)

• no solution

Solve using Elimination Method:

x - y = 11

2x + y = 19

• (10,-1)

• (-1,10)

• (3,-4)

• (6,7)

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

Answer explanation

10y-11x=-4

-2y+3x=4

• (2,2)

• (4,4)

• (4,8)

• (3,2)
