will medal


1. x+4=-9
2. 12- x=7
3. -5x=-35
4. x/4-5=6
5. 3(x-2)+5x=18
6. 8x-9=3x=16
7. -2/7+6+1/7x+18

Answer 1

One question per post please lol c:

Answer 2

1. -14. this is because if you take -14 and add +4 then it equals -9. Try to say what in place of the x. #2. 12-what=7? I hope this helped

Answer 3

1. x + 4 = -9 --- subtract 4 from both sides
x + 4 - 4 = -9 - 4
x = - 13

2. 12 - x = 7 --- subtract 12 from both sides
12 - 12 - x = 7 - 12
-x = - 5 -- multiply by -1 to make x positive
-1(-x) = -1(-5)
x = 5

3. -5x = -35 --- divide both sides by -5
(-5/-5)x = -35/-5
x = 7

4. x/4 - 5 = 6 --- add 5 to both sides
x/4 - 5 + 5 = 6 + 5
x/4 = 11 --- multiply both sides by 4
4(x/4) = 4(11)
x = 44

5. 3(x-2) + 5x = 18 -- distribute through the parenthesis
3x - 6 + 5x = 18 --- add 6 to both sides
3x - 6 + 6 + 5x = 18 + 6
3x + 5x = 18 + 6
8x = 24 -- divide both sides by 8
(8/8)x = 24/8
x = 3

6. you need to write this one over...there is a mistake in the problem

7. -2/7 + 6 + 1/7x + 18 --- combine like terms
(-2/7 + 6 + 18) + 1/7x
(-2/7 + 42/7 + 126/7) + 1/7x
166/7 + 1/7x....that's all you can do with this because there is no equal sign.
