Question

if the equation is an identity,write identity if has no solution rite no solution
show work lol
5.5-3b=2b-6.25

Answer 1

I dont think it's an identity equation but it has a solution which is 2.35

Answer 2

if it was identity then 5.5=-6.25; absurd.

Answer 3

5.5 - 3b = 2b -6.25 subtract 5.5 from both sides
-3b= 2b -6.25-5.5 combine and subtract 2b from both sides
-5b = -11.75 divide both sides by -5
b=2.35 this is a solution, therefore not an identity.

Answer 4

x + y = 8
2x + 2y = 16
2 equations with two unknown, but can't be solved as they are identities.
