Hi
GOAL is to Gather Like Terms, So We can Read:  ‘ x = Answer’
5x+8=3x+20 ,  {{{  highlight_green(2x=12) }}}  x = 6      
9a+4=2a+25 , {{{  highlight_green(7a=21) }}} a = 3
6n-5=3n+10 , {{{  highlight_green(3n=15) }}} n = 5
6y+7=4y-3 ,  {{{  highlight_green(2y= -10) }}} y = -5
12k+5=k+49,  {{{  highlight_green(11k=44) }}}  k = 4
 -3b+8=2b+48,  {{{  highlight_green(-40 = 5b) }}} b = -5
 5x-10=9x+26 , {{{  highlight_green(-36=4x) }}} x = -9
4q-15=6q-1 ,  {{{  highlight_green(-14 = 2q) }}}  q = -7
12-7t=30+2t , {{{  highlight_green(-18=9t) }}}   t = -2
10-3p=2+5p ,  {{{  highlight_green(8p=8) }}}  p = 1

-11y-4=11-8y ,  {{{  highlight_green(-15=3y) }}}  y = -3
8d=3d+60 , {{{  highlight_green(5d = 60) }}}  d = 12
-2m=16-m , {{{  highlight_green(-16=m) }}}  m = -16
15+6x=2-7x, {{{  highlight_green(13x = -13) }}} x = -1
No problem :)
grandmas age is four less than six times little pattys age if the sum of their age is 80 
x + (6x-4) = 80 
 7x = 84
  x = 12, Patty's Age.  Granma is 68   
                                                                                                                                                             joey weighs five pounds less thsn twice his brother. together they weigh 100 pounds.  
x + (2x-5) = 100lb
    3x = 105lb
     x = 35lb, bother's weight.  Joey wieghs 65lb                                                                                         an 30 meter cable is cut so that one piece is two meters less than three times the older. 
 x + (3x-2) = 30m
     4x = 32
      x = 8m, the shorter piece.  The longer piece is 22m
