Answer:
x = 4
Step-by-step explanation:
3x÷2=6
Multiply both sides by 2.
3x = 12
Divide by 3.
x = 4
 
        
                    
             
        
        
        
Add 2.38 and 4.89 then subtract 3 giving you 4.27

Answer:
   B) x = 2, y = 1
Step-by-step explanation:
Add the two equations to eliminate the x-variable.
   (x +3y) +(-x +6y) = (5) +(4)
   9y = 9 . . . . . . .simplify
   y = 1 . . . . . . . . divide by 9
You can substitute this value into either equation to find x.
   x + 3(1) = 5
   x = 2 . . . . . . . . subtract 3
The solution is (x, y) = (2, 1).
