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
