Answer: £18
Step-by-step explanation:
let Bridget get £x,
Stephen gets 3x, Richard gets 2(3x)
Equation is x + 3x + 6x = 60
10x = 60: x = 60/40 = 6
Bridget gets £6
Stephen gets 3x = 3 x 6 = £18
Richard gets 2(3x) = 2 x 18 = £36
 
        
             
        
        
        
12x+y=10 -----> 12x + y = 10
-3=3x+3y ------> -12x - 12y = 12 (multiplied by -4)
-11y = 22
y= -2
12x - 2 = 10
x = 1

The answer would be x+2 because you divide 6x+12 by the greatest common factor which is 6
        
             
        
        
        
I have no idea what in the world all those 9s are doing there,
but the decimal form of  69/25  is  2.76 .
