System of Equations Substitution and Elimination

Which method would be best (quickest) for solving the system below:

2x + 2y = 11

3x - 4y = -2

• Substitution

• Elimination

• Graphing

• None of these

Solve the system using substitution:

x + y = 19

y = 3x - 1

• (14, 5)

• (11, 8)

• (5, 14)

• (8, 11)

Solve the system using elimination:

3x + y = 19

2x - y = 6

• (5, 14)

• (4, 5)

• (5, 4)

• (14, 5)

Which method would be best (quickest) for solving the system below:
3x - 4y = -2
y = 2x + 1

• Substitution
• Elimination
• Graphing
• None

Solve the system:
x + 6y = 17
x - 3y = 8

• (5, 2)
• (11, 1)

Solve the system using substitution:

y = -1x - 5

4x - 8y = 4

• (-3, -2)

• (5, -7)

• (3, 9)

• (-5, 4)

Solve the systems using substitution:

y = 7x + 9

2y + 2x = -18

• (5, 0)

• (9, 18)

• (-2, -5)

• (1, 16)

Solve the system using substitution

y=8x+1

y=6x+3

• (1, 9)

Which variable will be eliminated?

• x

• y

Find x and y using the elimination method
2x+3y=7
2x+7y=11

• x=-2, y=-1
• x=2, y=-1
• x=2, y=1
• x=-2, y=1
