Answer: x = -0.3

Step-by-step explanation:

<u>Given expression</u>

1 - 3 (9x + 3) = 3x + 1

<u>Expand parentheses and apply the distributive property</u>

1 - 27x - 9 = 3x + 1

<u>Combine like terms</u>

(1 - 9) - 27x = 3x + 1

-8 - 27x = 3x + 1

<u>Subtract 3x on both sides</u>

-8 - 27x - 3x = 3x + 1 - 3x

-8 - 30x = 1

<u>Add 8 on both sides</u>

-8 - 30x + 8 = 1 + 8

-30x = 9

<u>Divide - 30 on both sides</u>

(-30)x / (-30) = 9 / (-30)

(-30)x / (-30) = 3 / (-10)

\boxed{x=-0.3}

Hope this helps!! :)
