X - 4 = 4
First you will start off by adding four on both sides

X-4=4
+4 +4
-4 +4 cancels out therefore it is now
X=8


I’m not too sure about the other as it kind of depends

The answer is (7,6)

This is because a midpoint is in the exact middle, meaning that both sides are an equal distance away. You can find this by fining the difference between the two corresponding coordinates then adding that difference to the midpoint and that will give you your other endpoint.

Hope this helped !!

I didn't understand this to be honest I thought I had to find what jm and lm were together and then subtract from the whole tota
prisoha [69]

Answer:

The correct answer is 3x-2

Step-by-step explanation:

It gives you the expression for JM and LM, and it asks for JL. Therefore, if you take away LM from JM, you are left with JL. You must subtract 2x-6 from 5x-8.

∴5x-8-(2x-6)

Do not forget to distribute the negative since you are subtracting, so instead of subtracting 6 from 8, you will be adding 6 to 8 because two negatives make a positive.
