2 (x + 5) = 2 (x + 3) + c

This problem is a bit weird but it's not that at all hard. Because of the c so I believe that what is it asking here is to find c

First you have to distribute

2x+10=2x+6+c

Then just eliminate the like term

10-6=2x-2x+c

4=c

4=c

I think it's right sorry if it's not I did it super quickly
