I need help bad I'm hella confused!

a. x=-7 b. -8 hope this helps with the rest of them.

Step-by-step explanation:

a you -28 divided by 4 to simplify x

b. this is a little harder because 6 is a double negative. when it has 2 minus signs that makes it a positive. we have to put 6 on the other side of the equal sign. so we have to minus 6 to put it on the other side. This is because on the left its positive so to put it on the right it has to be a negative. -6 plus -2 = -8. so x is = to -8

a negative exponent is translated as follows:

so, we have
