Question

What is (x)/(x-7)=(7)/(x-7)

Answer 1

Answer:

x/x-7=7/x-7

On comparing LHS with RHS, we get

x=7

Answer 2

Answer:

x=7

Step-by-step explanation:

x/(x-7) =7/(x-7)

by cross multiplying

x²-14x+49=0

by quadratic formula

x=-b±√b²-4ac/2a

x=-(-14) ±√(-14)²-4×1×49/2×1

x=14±√0/2

x=14/2

x=7
