Answer 2

It looks like you've provided a system of equations with absolute values. Let's solve them step by step:

1. $|x| + 3 = 5$

First, subtract 3 from both sides:

$|x| = 2$

This means that either $x = 2$ or $x = -2$, because the absolute value of both 2 and -2 is 2.

2. $|2x| + 3 = 9$

Subtract 3 from both sides:

$|2x| = 6$

This means that either $2x = 6$ or $2x = -6$.

For $2x = 6$, divide both sides by 2:

$x = 3$

For $2x = -6$, divide both sides by 2:

$x = -3$

So, there are two possible solutions for this equation: $x = 3$ and $x = -3$.

3. $3/7 + |4x| = 1+5$

First, simplify the right-hand side:

$3/7 + |4x| = 6$

Subtract $3/7$ from both sides:

$|4x| = 41/7$

This means that either $4x = 41/7$ or $4x = -41/7$.

For $4x = 41/7$, divide both sides by 4:

$x = 41/28$

For $4x = -41/7$, divide both sides by 4:

$x = -41/28$

So, there are two possible solutions for this equation: $x = 41/28$ and $x = -41/28$.

In summary, the solutions to the system of equations are:

$x = 2$, $x = -2$, $x = 3$, $x = -3$, $x = 41/28$, and $x = -41/28$.
