Question 52574
I am trying to come up with a answer to this equation?

2.7 + 0.8n = 4

Subtract 2.7 from both sides and you have:
  .8n =  4 - 2.7
  .8n =  1.3

Divide both sides by .8 and you have:
   1n = 1.3/.8
    n = 1.625

Check solution by substituting 1.625 for n in the original equation:
2.7 + .8n = 4
2.7 + .8(1.625)  = 4
2.7 +  1.3  = 4
