Question

Determine which equation is an identity or whether it has no solution.

Answer 1

There is only one equation. Are there supposed to be more?

Answer 2

a-4a=2a+1-5a @BlackLabel

Answer 3

This one has no solution

Answer 4

can u show me how its no solution ? @BlackLabel

Answer 5

OK well lets solve it by gathering like terms on both sides
a-4a=2a+1-5a
-3a=2a+1-5a

Answer 6

Did you follow so far? I just added/subtracted like terms

Answer 7

yes @BlackLabel

Answer 8

Ok will do the same thing for the left hand side
-3a=2a+1-5a
-3a=-3a+1

Answer 9

Ok @BlackLabel

Answer 10

Does anything seem weird about -3a=-3a+1 @Selena2345

Answer 11

No @BlackLabel

Answer 12

Ok well then lets continue solving
lets add 3a to both sides
3a-3a=-3a=3a+1
0=1
CAN 0 EQUAL 1???????
