Question

if gcf (25,15) =4x+1then x=___​

Answer 1

Answer:

x=1

Step-by-step explanation:

25=5*5

15=5*3

gsf=5

4x+1=5

4x=4

x=1

Answer 2

Given,

The equation for solving is , GCF (25,15) = 4x+1

To find,

The value of x in the given equation.

Solution,

At first, we need to calculate the value of GCF which is mentioned in the LHS of the given equation,in order to simplify the equation.

GCF (Greatest Common Factor) :

25,15

Prime factors :

25 = 5×5

15 = 5×3

So,the GCF of the given numbers is 5.

And,the value of LHS of the given equation is also 5.

The equation,

5 = 4x+1

Or, 4x+1 = 5

4x = 4

x = 1

Hence,the value of x in the given equation is 1.
