Answer: No

Explanation:

1 + 4(3x - 10) - 12x = 9

simplifies to

1+12x - 40 -12x =9

combine like terms to get

-39 = 9

This is not possible so the answer is no.

Answer:

Since you have to distribute the 4 to both terms in parentheses, the equation is simplified like this:

1 + 12x - 40 -12x

= 1 - 40

= -39
