find value of x if 7x-3 *52x-8​  = 1225

7x-3 * 52x-8 = 1225

after prime factorization of RHS ..

7x-3 * 52x-8 = 5*5  *  7*7

7x-3 * 52x-8 = 52  *  72

that implies :-

7x-3= 72

that implies ;-


x-3=2

that implies 

x =  3 + 2   =  5

and we can also find it from 5as we did it with 72 . the answer will be the same .
