All you need to do is copy the letters and numbers from the figure for R, S, T, and U. It is as easy to do that as it is to copy from my answer here. For example,
R = (b/2, 0)

The point M is the midpoint of both SU and RT. Since it comes out the same either way, it doesn't matter which pair of points you use to find M. However, the "b+c+" in the first expression x-coordinate suggests you start with point S.

$M=\dfrac{S+U}{2}=\left(\dfrac{\left(\dfrac{b+c}{2}\right)+\left(\dfrac{e}{2}\right)}{2},\dfrac{\left(\dfrac{d}{2}\right)+\left(\dfrac{f}{2}\right)}{2}\right)\\\\M=\left(\dfrac{b+c+e}{4},\dfrac{d+f}{4}\right)$

Then the other expression for M will fill in as ...

$M=\left(\dfrac{c+e+b}{4},\dfrac{d+f}{4}\right)$

3/x+2 = 2/x−1 pleasee help

So you have:
$\frac{3}{x} + 2 = \frac{2}{x} - 1
$

1) Start off by multiplying both sides by x to simplify the problem:
$\frac{3}{x} + 2 = \frac{2}{x} - 1 \\
x(\frac{3}{x} + 2) = (\frac{2}{x} - 1)x\\
3 + 2x = 2 - x
$

2) Now isolate the x by moving all terms with x onto one side and all other terms onto the other side:
$3 + 2x = 2 - x\\
3x = -1$

3) Finally, divide by 3 on both sides to find the value of x:
$3x = -1\\
x = \frac{-1}{3}$

------

Answer: x = $\frac{-1}{3}$
