(5x+3)/(4x) = (x+1)/(x)

x is not equal zero (why?)

(5x+3) * x = 4x * (x+1)

5 x + 3 = 4 x + 4

x = 1

(5x+3)/(4x) = (x+1)/(x)

Method-1:
cross multiplying we get

(5x+3) * x = (x+1)*4x
5x^2 + 3x = 4x^2 + 4x
5x^2 + 3x - 4x^2 - 4x = 0
x^2 - x = 0
x*(x - 1) = 0
=> x = 0 or 1.

Substituting back the values of x, we see that x cannot be 0 because we get into the 'divide by zero' situation. Hence x = 1 is the only solution.

Method-2: (5x+3)/(4x) = (x+1)/(x)

Multiply 'x' on both sides we get,

(5x+3)/4 = x+1
5x+3 = 4(x+1)
5x+3 = 4x+4
5x-4x = 4-3
x = 1.

(5x+3)/(4x) = (x+1)/(x)
x(5x+3) = 4x(x+1)
5x^2 + 3x = 4x^2 + 4x
x^2 - x = 0
x(x-1) = 0
x = 0 or x = 1

x = 0 rejected because denominator cannot be 0.
Therefore, the only solution to the equation is x = 1.

First u cross-multiply, it becomes
x(5x+3) = 4x(x+1)
5xsq + 3x = 4xsq + 4
xsq + 3x - 4 = 0

Then you factorize and you get
x = 1 and x = -4

Good luck!

Both sides of the equations have a factor of x in the denominator. Start by multiplying both sides of the equation by 4x. Keep in mind that since you have x in the denominator the system is undefined if x = 0.

Good Luck
