Answer:2x-1
Step-by-step explanation:
Answer: you would do -16 - 5 = -21
Okay so for this one, we have to isolate our X.Lets start by moving the negative 5 on the other side of the equal sign. Remember to not mix a number that is with an X with a normal number (in this case it would be the -3x and the -5). So in putting our -5 on the other sign it becomes positive. Here’s what we have: x^2-3x=5. x^2 is the same thing as 2x.So now you have to minus 3x off of your 2x. This gives us -1x, but can just be put as -x. So now we have -x=5. You’re answer could either be 5 or -5 if you decided to divide it by -1 seeing as your -x is technically -1.

Answer:
x = 19
z = 64
Step-by-step explanation:
Angles (11x - 93)° and 116° are vertical angles, so their measures are equal.
11x - 93 = 116
11x = 209
x = 19
Angles z° and 116° are a linear pair, so they are supplementary, and their measures have a sum of 180°
z + 116 = 180
z = 64
