Explanation:

After the Civil War, the country was still extraordinarily separated on the grounds that the South had been crushed physically and profoundly. Other than the annihilation of the land, homes, and urban communities, no Confederate officers were permitted entombment in Arlington Cemetery, and huge numbers of their bodies were lost to their families. Carpetbaggers, go getters from the north, and rapscallions cheated individuals out of their property, abused poor people, unskilled, and gullible previous slaves, giving them bogus guarantees and controlling them for their very own political purposes.  

It is just in the twentieth century that the South has again turned into an economic power. All things considered, numerous Southern states are among the most unfortunate states in the country. The President in charge of a larger number of passings of American officers than any president in U.S. history was executed before he could correct in any genuine manner other than liberation the damage done to America.

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
