    Answer:

    No

    Step-by-step explanation:

    We can’t use 2x + c = d for solving 2x + 1 = 9 . Here we can find the value of x from 2x + 1 = 9.

    2x + 1 =9\\=>2x=9-1\\=>2x=8\\=>x=4

    Putting the value of x in 2x + c = d :-

    2x+c=d\\=>2*4+c=d\\=>8+c=d

    But still we don’t know the exact value of c & d . If in the question at least we could have got one exact value of either c or d , then we could find out the value of other variable.
