Answer:
b = 5.
Step-by-step explanation:
-3(6 + 6b) + 4 = -104
-18 - 18b + 4 = -104
-18b = -104 + 18 - 4
-18b = -90
b = -90 / -18
b = 5.

Answer:
x + y = 500
215x + 615y = 187,500
Step-by-step explanation:
The first equation can show the amount of land. The farmer has 500 acres to plant corn, x, and cotton, y.
x + y = 500
The second equation can show the cost. The farmer has $187,500 to invest when corn costs $215 per acre and cotton costs $615 per acre.
215x + 615y = 187,500
The system of equations is
x + y = 500
215x + 615y = 187,500
