Answer 3

Let's solve each equation step by step:

1. $7 + x = 4$:

Subtract 7 from both sides to isolate $x$:

$x = 4 - 7$

$x = -3$

So, the solution for the first equation is $x = -3$.

2. $-24 - y = -163$ or $|x| - 4 = 5$:

a) $-24 - y = -163$:

Add 24 to both sides to isolate $y$:

$y = -163 + 24$

$y = -139$

So, the solution for the second equation (the left side) is $y = -139$.

b) $|x| - 4 = 5$:

Add 4 to both sides:

$|x| = 9$

Now, $x$ can be either 9 or -9 since the absolute value of either is 9.

So, the solutions for the second equation (the right side) are $x = 9$ or $x = -9$.

Therefore, the combined solutions for the second equation are $y = -139$ and $x = 9$ or $x = -9$.
