Simplifying
5x + 4 = x + 44

Reorder the terms:
4 + 5x = x + 44

Reorder the terms:
4 + 5x = 44 + x

Solving
4 + 5x = 44 + x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1x' to each side of the equation.
4 + 5x + -1x = 44 + x + -1x

Combine like terms: 5x + -1x = 4x
4 + 4x = 44 + x + -1x

Combine like terms: x + -1x = 0
4 + 4x = 44 + 0
4 + 4x = 44

Add '-4' to each side of the equation.
4 + -4 + 4x = 44 + -4

Combine like terms: 4 + -4 = 0
0 + 4x = 44 + -4
4x = 44 + -4

Combine like terms: 44 + -4 = 40
4x = 40

Divide each side by '4'.
x = 10

Simplifying
x = 10

Answer:

Step-by-step explanation:

We have the two functions:

$f(x)=\sqrt{x}+12\text{ and } g(x)=2\sqrt{x}$

And we want to find (f-g)(144).

This is the same thing to f(144)-g(144).

So, let’s determine the value of f(144) and g(144) first:

$\begin{aligned} f(144)&=\sqrt{144}+12 \\ &=12+12 \\ &=24\end{aligned}$

And:

$\begin{aligned} g(144)&=2\sqrt{144} \\ &=2(12) \\ &=24 \end{aligned}$

Hence:

$\begin{aligned} (f-g)(144) &= f(144)-g(144) \\ &=24-24 \\ &=0 \end{aligned}$

Our final answer is 0.

X/x+9 (original fraction)

x+1/ x+10 = 4/13

x+1=4 so x=3 and x+10=13 so again x=3

now that you have the value of x, substitute it into the original fraction to get:

3/12
