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)
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)
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
