(9b-3)/9 =(5b+5)/3

\frac{9 b - 3}{9} = \frac{5 b + 5}{3}

b = - 3

Solution steps

\frac{9 b - 3}{9} = \frac{5 b + 5}{3}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(9 b - 3) \cdot 3 = 9 (5 b + 5)

Expand

(9 b - 3) \cdot 3 : 27 b - 9

Expand

9 (5 b + 5) : 45 b + 45

27 b - 9 = 45 b + 45

Move

9

to the right side

27 b = 45 b + 54

Move

45 b

to the left side

- 18 b = 54

Divide both sides by

- 18

b = - 3

y = - 2 (0) + 3

25 = 21 - 4 x

- 10 - 7 x = 32

x, x - y = 16

- 6 x = - 42
