Solve 3 – 2(b – 5) = 7. Or is the equation an Identity? Or if it has any solution at all? I want help to solve it more than the straight answer.

Best ResponseYou've already chosen the best response.0okay so you can start of by distributing the 2 into (b  5) do you know how to do that?

Best ResponseYou've already chosen the best response.0okay so now you should have 2b + 13 = 7

Best ResponseYou've already chosen the best response.0Okay so 132b=7. Then subtract 13 from both sides?

Best ResponseYou've already chosen the best response.02b = 6. So then divide 6 by 2, making b=3, correct?

Best ResponseYou've already chosen the best response.0@rhr12 that would make it an identity, correct? If it is correct, @watchpencilpaper?

Best ResponseYou've already chosen the best response.0you cant subtract the 2 from the 3 before multiplying it by the (125) so its wrong

Best ResponseYou've already chosen the best response.0lets just continue solving the equation and then we can check our answer so we left of at 2b = 6 right?

Best ResponseYou've already chosen the best response.0yes okay and we can check that by plugging it back into our equation \[3  2(b5) = 7\] \[3  2((3)5) = 7\] \[3  2(2) = 7\] \[3  (4) = 7\] \[3 + 4 = 7\] \[7 = 7\]
