Answer 4

not quite, 2-3= -1

Answer 5

so once you subtract 3 from both sides your equation will look like this:
1/4x= -1. Do you know what to do next?

Answer 6

no

Answer 7

ok, so you want to get x by itself, so you need to multiply both sides of the equation by 4. So your answer is x= -1(4)

Answer 8

thank you know how do i do it when it looks like this
-1y= -4

Answer 9

yes, you need to multiply both sides of the equation by -1 in that equation to get y by itself so its -1(-4)

Answer 10

remember a negative*negative= a positive

Answer 11

so the answer is 4 right ?

Answer 12

correct! :)

Answer 13

x+5=15
is x ten ?

Answer 14

i mean id dint do anything just geussing

Answer 15

yepp!

Answer 16

no its 1.000.000

Answer 17

you subtract 5 from both sides so its x=15-5 which is 10

Answer 18

6y + 1 = -11
on which side do i mulitply

Answer 19

you don't multiply, first subtract 1 from both sides, what do you get?

Answer 20

-10

Answer 21

not quite, its -11-1, so its like adding -1 + -11 which equals -12

Answer 22

so your equation then looks like this: 6y= -12, next step is to divide both sides by 6, so what is -12/6

Answer 23

sorry im little stupid lol

Answer 24

no you're not(:

Answer 25

-2

Answer 26

correct so y= -2

Answer 27

1/4 b = -3
will you help me lol theres only 3 more questions i just need somebody to go through them with me

Answer 28

ok sure, so for this one you need to first multiply both sides of the equation by 4 to get b alone, so what is 1/4(4) ?

Answer 29

1

Answer 30

correct, now what is -3(4) ?

Answer 31

-12

Answer 32

correct, so b= -12

Answer 33

-4x=-20

Answer 34

ok for this one first divide both sides by -4, so what is -20/-4 ?

Answer 35

5

Answer 36

correct x=5

Answer 37

1/2 z =10

Answer 38

ok multiply both sides by 2, so 10(2)

Answer 39

20

Answer 40

correct z=20

Answer 41

-7x-8=-36
Last one (:
you helped me so much thank you i was working on this test for weeks and failed so many times

Answer 42

no problem!(: ok so for this one first you need to add 8 to both sides, so what is -36+8? (its basically like doing 36-8 and adding a negative in front of it)

Answer 43

-28

Answer 44

correct so its -7x= -28, so what is -28/-7 ?

Answer 45

4

Answer 46

correct so x=4
