Answer 2

I see you've got a couple of equations there. Let's simplify them:

1. $3x + 5 - x = 2 - 15$

Combining like terms on the left side:

$2x + 5 = -13$

Subtracting 5 from both sides:

$2x = -18$

Dividing both sides by 2:

$x = -9$

Now, for the second one:

2. $94y - 5y + 4 = 2 \times \frac{5 - 3}{12} \times 8$

Combining like terms on the left side:

$89y + 4 = \frac{2 \times 2}{12} \times 8$

Simplifying the right side:

$89y + 4 = \frac{4}{3} \times 8$

$89y + 4 = \frac{32}{3}$

Subtracting 4 from both sides:

$89y = \frac{32}{3} - 4$

$89y = \frac{32}{3} - \frac{12}{3}$

$89y = \frac{20}{3}$

Dividing both sides by 89:

$y = \frac{20}{267}$

So, $x = -9$ and $y = \frac{20}{267}$.
