Question

19x/x+9 =x+9/x find x

Answer 1

Answer:

X=.5

Step-by-step explanation:

First, I rewrite the equation:

$\frac{19x}{x+9}$= $\frac{x+9}{x}$

Next, Cross Multiply:

19x times x is 19x^2

x+9 times x+9 equals (x+9)^2

Write the Formula Again, Revised:

19x^2=(x+9)^2

Square Root Both Sides:

19x=x+9

Subtract x from both sides:

18x=9

Divide Both Sides by 18:

X=.5

.5 is the answer

i hope this helps!
