So if 18 + x =43, then what you need to do is 
 18 + x =43
-18 -18
——————
 x = 25
because whatever you do to one side, you need to do to the other
        
             
        
        
        
Answer:
 {x,y} = {3,-2} 
Step-by-step explanation:
// Solve equation [1] for the variable  y 
 
  [1]    y = 2x - 8
// Plug this in for variable  y  in equation [2]
   [2]    3x - 2•(2x-8) = 13
   [2]    -x = -3
// Solve equation [2] for the variable  x 
   [2]    x = 3 
// By now we know this much :
    x = 3
    y = 2x-8
// Use the  x  value to solve for  y 
    y = 2(3)-8 = -2 
Solution :
 {x,y} = {3,-2}

Answer:
50
Step-by-step explanation:
you need to put  first the 32 on top of 100 since it always goes over 100 then you put 16 over a blank and you divide 32 by 16 which equals 2 so since you divided at the top you need to divide at the bottom so you divide 100 by 2 and you get 50 so 50 is your answer
