I am guessing that these are true in some unknown base, i.e.
4 + 6 = 2(x) + 0
x = 5
So in base 5, 4+6 = 20
You try the second one, using a similar argument
Find the base of each of these operation
a)4+6=20
b)3*7=23

3*7=23 in binary
Find it base 4+6=20.
In the equation below,solve for x of all the numbers are given in base 2. 11/x=1000/x+101
