Explain why Oklahoma's plains were slowly enclosed as ranchers began to embrace closed-range ranching. In your answer, identify at least two factors that caused this change to take place.

First and foremost, tenants did not own land or the crops they grew in a sharecropping system. Tenants often were forced to hand their crops over to the landowner, who would sell the crops and share a small portion of the profits with the tenant. Secondly, tenants were at the mercy of the market. They often overproduced crops to try making a profit on their own, which contributed to overblown supplies and falling prices. Finally, tenants often struggled with failing crops, failing land, and poor weather. Faced with debt to their landowners, tenants would be pressured to overcome these challenges while sometimes making choices that made the problem worse.

the perimeter of a triangle is 69 cm. side a is 5 cm shorter than side b. side c is twice as long as side a. find the length of each side. i need to know how to do it in 2 equations.  

equations:

a = b-5

c = 2a

a + b + c = 69
