(x+6)(x+3)=x(x+8)

(x + 6) (x + 3) = x (x + 8)

x = - 18

Solution steps

(x + 6) (x + 3) = x (x + 8)

Expand

(x + 6) (x + 3) : x^{2} + 9 x + 18

Expand

x (x + 8) : x^{2} + 8 x

x^{2} + 9 x + 18 = x^{2} + 8 x

Move

18

to the right side

x^{2} + 9 x = x^{2} + 8 x - 18

Subtract

x^{2} + 8 x

from both sides

x^{2} + 9 x - (x^{2} + 8 x) = x^{2} + 8 x - 18 - (x^{2} + 8 x)

Simplify

x = - 18

b, c = y + b

\frac{x}{3} - 2 = \frac{2}{5} x + \frac{1}{4}

f = (\frac{1}{2})^{- 3}

b, 4 y - 12 b = 3 c + 2 y

7 x + 30 = x + 6 (x + 5)
