Hi,

1. If 3x = 2x – 4,  x = -4, ⇒ 4x + 2 = -14 

2.The difference between a number, n, and twenty-seven is ten.  n-27+=+10



property of levers” %28W%5B1%5D%29%28D%5B1%5D%29+=+%28W%5B2%5D%29%28D%5B2%5D%29

 74.4x = 186(14-x)

 260.4x = 2604

      x = 2604/260.4 = 10ft from the child the fulcrum should be placed
