2.      Describe a consistent system.

3.      Describe an inconsistent system.

4.      Describe a dependent system.

Solve the following systems of equations using the graphing method.

What type of system is it? Name the solution if there is one.

1. x + y = 5
-x + y = 3

2. 2x – 2y = 8
x – y = 4

3. 3x – y = -2
3x – y = 4

4. y = 6
x = -3

Solve the following systems of equations using the substitution method.

What type of system is it? Name the solution if there is one.

1. x = 6y + 2
3x – 18y = 4

2. x – y = 3
x + 3y = 6

3. y = -2x
4x – 3y = 12

4. 2x – 5y = 15
x – 7y = 3

Solve the following systems of equations using the addition (elimination) method.

What type of system is it? Name the solution if there is one.

1. x + y = 6
x – y = 4

2. -2x + 3y = 5
2x – y = 1

3. 5x + y = 2
3x + y = 1

4. 5x = 20 + y
16 = 3y + 4x

Solve the following systems of inequalities using the graphing method.

1. x + y > 4
y + 3x < 6

2. x ≥ 5
y < 3

3. 3x – 2y > 8
-2y + 3x < 12

4. 2x + y < 8
x ≥ 4
