Answer 2

It seems like you've provided a couple of equations. Let's solve them step by step:

1. $\frac{1}{3}x = 72$

To solve for $x$, you can multiply both sides of the equation by 3 to isolate $x$:

$x = 72 \times 3$

$x = 216$

So, the solution for the first equation is $x = 216$.

2. $5x - 4.5 = 3x + 2.5$

First, let's simplify the equation by subtracting $3x$ from both sides:

$5x - 3x - 4.5 = 2.5$

$2x - 4.5 = 2.5$

Now, add 4.5 to both sides to isolate $2x$:

$2x = 2.5 + 4.5$

$2x = 7$

Finally, divide both sides by 2 to solve for $x$:

$x = \frac{7}{2}$

So, the solution for the second equation is $x = \frac{7}{2}$, which is equivalent to $x = 3.5$.

In summary:

1. $x = 216$
2. $x = 3.5$ or $x = \frac{7}{2}$
