(x-1)/2 =(x-9)/(11)

\frac{x - 1}{2} = \frac{x - 9}{11}

x = - \frac{7}{9}

Solution steps

\frac{x - 1}{2} = \frac{x - 9}{11}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(x - 1) \cdot 11 = 2 (x - 9)

Expand

(x - 1) \cdot 11 : 11 x - 11

Expand

2 (x - 9) : 2 x - 18

11 x - 11 = 2 x - 18

Move

11

to the right side

11 x = 2 x - 7

Move

2 x

to the left side

9 x = - 7

Divide both sides by

9

x = - \frac{7}{9}

\frac{- 4}{- 8}

ln (1.3)

10 x - 79 = 2 x + 49

2 x^{2} - 2 x = 0

5 x^{2} - 20 x + 3 = 0
