If x 2 – 15x + 51 = 0, then determine the value of (x – 5) + {1/(x – 5)}.
If a +`1/b` = 1 and b +`1/c` =1 , then the value of c +`1/a` is
22% of ‘x’ is equal to 66% of ‘y’, then find the value of x: y.
If AB = x + 3, BC = 2x and AC = 4x − 5, then for what value of ‘x’ does B lie on AC?
Find the value of ‘x’ in the given expression:
(49/16)x× (64/343)x-1 = 4/7
If x + 1/x = 5 then find out the value of x⁵ + 1/(x⁵)?
If (a + b) = 1 and (1/a) – 2b = 5/a then find the value of a2 + b2.
