Answer 2

To solve the given equations, let's work through each one step by step:

Equation 1: $3 | x + 1 | - 7 = 6.5$

First, add 7 to both sides:

$3 | x + 1 | = 13.5$

Now, divide by 3:

$| x + 1 | = 4.5$

This means $x + 1 = \pm 4.5$.

1. For $x + 1 = 4.5$, subtract 1 from both sides:

$x = 4.5 - 1$ $x = 3.5$

2. For $x + 1 = -4.5$, subtract 1 from both sides:

$x = -4.5 - 1$ $x = -5.5$

So, the solutions for the first equation are $x = 3.5$ and $x = -5.5$.

Equation 2: $2(x - 3) = 3x - 1$

First, distribute the 2 on the left side:

$2x - 6 = 3x - 1$

Next, move all terms involving $x$ to one side and constants to the other side:

$2x - 3x = -1 + 6$ $-x = 5$

Now, multiply by -1 to solve for $x$:

$x = -5$

The solution for the second equation is $x = -5$.
