I'm assuming that you meant 4x+1=3x?
Subtracting 4x, we get 1=-x. Multiplying by -1, we get x=-1 as the solution.
E x p e r i m e n t
Total number of letters = 10
Repeated letters = 3 e
Total arrangement from the 10 letters = 10!
Because of the repeated letters = 10! / 3!
= (10 × 9 × 8 × 7× 6 × 5 × 4 × 3!) / 3!
= 10 × 9 × 8 × 7× 6 × 5 × 4
= 604800
604800 distinct arrangements.
