The expression 3x+4 = 3x+4 has how many solutions?

No solution

Explanation:

You can't cancel out the "X" because it would equal zero since the equations equaled to eachother are the same! :)

replace   c   with   a   and simplify.

a = c , b = a, q = n , 2 , a = c , 900 b= a , 700 , q = n , 600 , 2 = b o t h , b = a , q = n
