If 1/4 + 1/x = 1 , then x is equal to

x=4/3

Step-by-step explanation:

multiply by least common multiple of 4x.

1/4*4x+1/x*4x=1*4x

simplify.

x+4=4x

subtract 4 both sides of an equation.

x+4-4=4x-4

simplify.

x=4x-4

subtract by 4x both sides of an equation.

x-4x=4x-4-4x

simplify.

-3x=-4

divide by -3 both sides of an equation.

-3x/-3=-4/-3

simplify.

x=4/3 its changes to be positive fraction as an answer.

Hope this helps!

Thanks!

Have a great day!
