Evaluate the expression and give your answer in standard form: (-6(7+-3)--(15+3)+9)/(3x-8+-19x4).

Here are the solutions to your problems:

1. Evaluate the expression and give your answer in standard form.
The expression is $\frac{-6(7+-3)--(15+3)+9}{3x-8+-19\times4}$.

Assumption 1: The 'x' in the denominator $3x-8$ is a multiplication sign, so $3 \times 8$. This is assumed because the instruction is to "evaluate" to a numerical answer in "standard form".
Assumption 2: The double minus sign "--" in the numerator means a positive sign, as in a double negative.

Step 1: Evaluate the numerator.

$$-6(7+-3)--(15+3)+9$$ $$= -6(7-3) + (15+3) + 9$$ $$= -6(4) + (18) + 9$$ $$$$
