the answer is a
Yes because if 1+0=1 than 0 plus b equals b
a= (+a) or a= (-) b= 2a b= 2a c= (-a) c= (+a)
a=24 b=16 c=18
Because there is no way to define the divisors, the equations cannot be evaluated.
Plugging the numbers into the equation gives b = -22.
it is the associative property
b = 6
2a. (a, b and c are all equal.)
b positive :)
a + b = c
a = 11 and b = 5.
b + b + b + c + c + c + c = 3b + 4c
