Answer:

$\text{a. }x=7, x=-7, \\\text{b. }x=16, x=-16, \\\text{c. }x=3, x=-17, \\\text{d. }x=7, x=-7$

Step-by-step explanation:

For $|x|=y$ , we have two cases:

$\begin{cases}x=y, \\x=-y\end{cases}$

Using this, we can solve all four of the problems:

$\text{a. }|x|=7,\\\begin{cases}x=7, \\x=-7\end{cases}$

$\text{b. }|2x|=32,\\\begin{cases}x=16, \\x=-16\end{cases}$

$\text{c. }|x+7|=10,\\\begin{cases}x+7=10, x=\boxed{3,} \\x+7=-10, x=\boxed{-17}\end{cases}$

$\text{d. }5|x|=35,\\\begin{cases}x=7, \\x=-7\end{cases}$

Answer:

Part A) plot 1 and -2.5.

B) The opposite of 2 is -2. The only number that has its own opposite is 0. The first statement is false.

The opposite of 1.5 is -1.5, so the opposite of the opposite of 1.5 is equal to the opposite of -1.5, which is 1.5. The second statement is true.
