Solve the system of equations using any method. Explain why you chose this method.

• Infinitely Many Solutions

• (0, 6)

• (-1, 4)

• (12, -5)

Solve the system of equations using the substitution method.

• (-7, 4)

• Infinitely Many Solutions

• (13, -5)

• (0, -8)

Define the variables, set up a system of equations and solve using the substitution method.

• 4 cm by 13 cm

• 6 cm by 11 cm

• 9 cm by 5 cm

• 8 cm by 7 cm

Define the variables, set up a system of equations and solve using the substitution method.

• 6 dimes & 11 quarters

• 5 dimes & 13 quarters

• 8 dimes & 4 quarters

• 7 dimes & 12 quarters

Answer the following question and explain your answer.

• Always

• Sometimes

• Never

Define the variables, set up a system of equations and solve using the substitution method.

• corn: 146 acres; tomatoes: 123 acres; sunflowers: 61 acres

• corn: 152 acres; tomatoes: 112 acres; sunflowers: 56 acres

• corn: 117 acres; tomatoes: 98 acres; sunflowers: 42 acres

• corn: 134 acres; tomatoes: 114 acres; sunflowers: 84 acres

When solving the system, if you get a result of something like 6 = 6 or -2 = -2 and the answer is:

• No Solution

• Infinitely Many Solutions

• Not possible

What is the solution to the system of equations? 
y = 3x - 8
y = 4 - x

• (3,1)

• (1,3)

• (-3,1)

• (3,-1)

Solve for x and y
3x + 2y = 16
7x + y = 19

• (-2,5)

• (-2,-5)

• (2,-5)

• (2,5)
