Consider the order of operations

1) parenthesis indicate &quot;do me first&quot;
2) execute division and multiplication from left to right, then addition and subtraction from left to right

your problem asks

2x +3 (4x +5)= 1

x-5= 4x+19 
4x-5= 2x +17 
-4x+8= 2x-16 
16+2x =4x-8


1) 2x +3 (4x +5)= 1
   2x +12x+15=1         here we multiply (4x+5) by 3
   14x = -14            subtract 15 from both sides of =, combine like terms
     x = -1             divide both sides of = by 14

2) x-5= 4x+19
   -3x = 24
     x = -8

3) 4x-5= 2x +17
     2x=22
      x=11

4) -4x+8= 2x-16
     -6x= -24
       x=4

5) 16+2x =4x-8
      -2x=-24
        x=12
