(-1)/(5-sqrt(1/5*x+1))= 17/10

Solution

\frac{- 1}{5 - \frac{1}{5} \cdot x + 1} = \frac{17}{10}

Solution

x = \frac{43680}{289}

Decimal Notation

x = 151.14186 \dots

Solution steps

\frac{- 1}{5 - \frac{1}{5} x + 1} = \frac{17}{10}

Apply fraction cross multiply: if

\frac{a}{b} = \frac{c}{d}

then

a \cdot d = b \cdot c

(- 1) \cdot 10 = (5 - \frac{1}{5} x + 1) \cdot 17

Expand

(5 - \frac{1}{5} x + 1) \cdot 17 : 85 - 17 \frac{1}{5} x + 1

(- 1) \cdot 10 = 85 - 17 \frac{1}{5} x + 1

Switch sides

85 - 17 \frac{1}{5} x + 1 = (- 1) \cdot 10

Remove parentheses:

(- a) = - a

85 - 17 \frac{1}{5} x + 1 = - 1 \cdot 10

Multiply the numbers:

1 \cdot 10 = 10

85 - 17 \frac{1}{5} x + 1 = - 10

Move

85

to the right side

- 17 \frac{1}{5} x + 1 = - 95

Divide both sides by

- 17

\frac{1}{5} x + 1 = \frac{95}{17}

Square both sides:

\frac{1}{5} x + 1 = \frac{9025}{289}

\frac{1}{5} x + 1 = \frac{9025}{289}

Solve

\frac{1}{5} x + 1 = \frac{9025}{289} : x = \frac{43680}{289}

x = \frac{43680}{289}

Verify Solutions:

x = \frac{43680}{289}

True

The solution is

x = \frac{43680}{289}

x - 1 = 2

sqrt(x-1)=8

x - 1 = 8

sqrt(x)+sqrt(x-\sqrt{x)}=1

x + x - x = 1

sqrt(x/((1-x)))+sqrt(((1-x))/x)= 21/6

\frac{x}{( 1 - x )} + \frac{( 1 - x )}{x} = \frac{21}{6}
