Is -8 - 2(3 + 2x) + 7x equivalent to -30 -13x?

They are NOT equivalent.

Step-by-step explanation:

To find if the expressions are equivalent, we have to simplify the first expression.

Solve:

-8 - 2(3 + 2x) + 7x

Use the distributive property.

-8 - 6 - 4x + 7x

Combine like terms.

-14 - 4x + 7x

-14 + 3x

Since they're not the same, this means that the expressions are NOT equivalent to each other.
