If `100-= x(mod 7),` then least positive value of x is

Find the least positive value of x if 5x -= 2 (mod 13)

If 3x=5 (mod 7) then

If 3x=5(mod7) , then:

If (3-x) -=(2x-5) (mod 4) then one of the values of x is

The greatest integral value of a such that sqrt(9-a^(2)+2x-x^(2))>=sqrt(16-x^(2)) for at least one positive value of x is (a) 3 (b) 4 (c) 6 (d) 7

The greatest integral value of a such that sqrt( 9 - a^2 + 2x - x^2) >= sqrt(16 - x^2) for at least one positive value of x is (a) 3 (b) 4 (c) 6 (d) 7

If 6x -= 5 (mod 7), then find x.
