Answer 1

Answer:

The answer is below

Step-by-step explanation:

1) -3x = 42

Divide both sides by -3

-3x/ -3 = 42 / -3

x = -14

Answer: p.x=-14

2)

$\frac{x}{-6}=-9\\ \\Multiply\ both\ sides\ by\ -6\\\\\frac{x}{-6}*-6=-9*-6\\\\x=54$

Answer: j. x=54

3) 5x = 105

Divide both sides by 5

5x/ 5 = 105 / 5

x = 21

Answer: n. x=-21

4) x+37=-25

add -37 to both sides

x+37 - 37 =-25 - 37

x = -62

Answer: d. x=-62

5) x-42=-15

add 42 to both sides

x-42 + 42 =-15 + 42

x = 27

Answer: k. x=27

6)x - (-12) = -4

x + 12 = -4

add -12 to both sides:

x + 12 - 12 = -4 - 12

x = -16

Answer:  f. x = -16

7) x - (-6) = 5

x + 6 = 5

add -6 to both sides:

x + 6 - 6 = 5 - 6

x = -1

Answer:  r. x = -1

8)8-x = -12

8 - x + x + 12 = -12 + x = 12

x = 8 + 12

x = 20

Answer: c) x = 20

9) -9 - x = -6

x = -9 + 6

x = -3

Answer: s. x =-3

10) -6 + x = 17

x = 17 + 6

x = 23

Answer: a. x =23

11)

$\frac{x}{9} =-42\\multiply\ by \ 9\\\\x = 9*-42=-378$

Answer: b. x = -378

12) -16 = x - 8

x = -16 + 8

x = -8

Answer: q. x = -8

13) -25 = x + 17

x = -25 - 17

x = -42

Answer: h. x = -42

14) 36 = 8 - x

x = 8 - 36

x = -28

Answer: g. x = -28

15) -x + 6 = 11

x = 6 - 11

x = -5

Answer: m. x = -5

16) -x + 8 = 4

x= 8 - 4

x = 4

Answer: e. x =4

17) 16 = 4 -x

x = 4 - 16

x = -12

Answer: o: x = -12

18) 85 = -5x

x = 85/ -5

x = -17

Answer: l. x= -17

19) 21 = -x/7

x = 21 * -7

x = -147

Answer: i. x = -147
