I've done math problems like this before but can't remember what to do. how do i work out 5c+1=7c-8

You would move the 7c to the left side

next , collect the like terms which are 5c and 7c ,and that would equal -2c

then you would do -8-1 which equals -9

then divide both sides of the equation by -2

then answer is c= 9/2

Letter b hope it
