Question

If G.C.F ( 25,15) = 4x + 1 then x = ....................‌​

Answer 1

ANSWER ::

The answer is x = 1

EXPLANATION ::

GCF ( 25,15) =5

So

G.C.F ( 25,15) = 4x + 1 gives

5 = 4x + 1

4x + 1 = 5

4x = 4

x = 1

Answer 2

Given,

The equation is, G.C.F (25,15) = 4x+1

To find,

The value of x.

Solution,

In order to simplify the equation,we need to solve the G.C.F of the left side of the given equation.

So,

G.C.F (Greatest Common Factor)

= 25,15

Prime factors :

25 = 5×5

15 = 5×3

So,the G.C.F = 5

Now,by putting the value of the G.C.F in the left hand side of the given equation,we get that,

5 = 4x + 1

4x + 1 = 5

4x = 4

x = 1

Hence,the value of the x is 1
