Let

x = 6 + \dfrac1{2 + \dfrac1{6 + \dfrac1{2 + \cdots}}}

Then

x = 6 + \dfrac1{2 + \dfrac1x}

and solving for x gives

x = 6 + \dfrac x{2x + 1}

x = \dfrac{13x + 6}{2x + 1}

x(2x+1) = 13x + 6

2x^2 + x = 13x + 6

2x^2 - 12x - 6 = 0

x^2 - 6x - 3 = 0

By the quadratic formula,

x = 3 \pm 2\sqrt{3}

but x must be a positive number, so only the positive square root solution is valid.

x = 3 + 2\sqrt{3}

We identify a = c = 3 and b = 2, so a + b + c = 8.

What value of x makes the equation true? 4x - 3= -9 + 7x
uysha [10]

Answer:

x = 2

Step-by-step explanation:

To find the x-value that makes the equation true, we would have to solve for x in the equation. To do that, we would have to get the equation in the form x = _. That would be our answer.

4x - 3 = -9 + 7x

Add 9 to both sides to get rid of the -9 on the right side.

4x - 3 + 9 = 7x

Simplify.

4x + 6 = 7x

Subtract 4x from both sides to get rid of the 4x on the left side.

6 = 7x - 4x

Simplify.

6 = 3x

3x = 6

Divide both sides by 3 to get rid of the coefficient of 3 on the left side.

x = 6/3

Simplify.

x = 2

So, the x-value that makes the equation true would be 2.

I hope this helps. :)
