(2,13) is a solution to the equation y=3x+7.
The answer is 36, because when you divide 80/20 it is going to be 4 and 9*4 is 36!
I think that the answer is: 2, 896
If it is wrong I’m so so sorry..
Robin’s number ------------ Y
Sydney’s number ------------ x
Y = X + 8.............. (1)
X + Y = 72 ............(2)
Substituting (1) in (2)
X + (X + 8) = 72 .............> ......2X = 64 => X = 32
Now in (1)
Y = (32) + 8 = 40
Robin is 40
Sydney is 32
