Answer 1

you probably should ask your teacher or someone else who can show you how to do it person to person.
i'll show you an example of each on how to find pronumerals of an equation and rearrange of an equation. that is as far as i would go.
finding a pronumeral (i'll use Q.1 as an example)

4x – 7 = -3(6 – 1)
expand the equation: 4x - 7 = -18+3
rearrange the pronumerals and numbers: 4x = -18+3+7
therefore 4x = -8
divide both sides by 4 (i hope you know why): x = -2
therefore x is -2

rearranging a pronumeral (i'll use Q.10 as an example)
y = mx + b, solve for x
put x (and anything that is attached in front of it) to one side and the other pronumerals to the other: mx = y - b
divide both sides by m: x = (y -b) divided by m
therefore a is the correct answer.

if you understand how to do the basics, like in the examples (there are different ways of doing it), then you should be able to complete your homework.

Answer 2

are u seriously hoping for people to answer your entire assignemnt? if u dont no neof this u should tlk to ur teacher bc then for a test ur gonna b screwed

Answer 3

first one is -2 but the rest you should prolly learn to do on ya own.

Answer 4

do your own homework or go ask your teacher for help that is what they are getting paid for

Answer 5

See my previous answer. Nice try, though.

Answer 6

??????????????? Ask your teacher. You really need help. What do you think? like were goona do your school work for you?

Answer 7

4x-7=-3(6-1)
4x-7=-18+3
4x=-18+3+7
4x=-18+10
4x=-8
x=-8/4
x=-2

'etc.......

Answer 8

Or you could do your own homework...
