6 = a/4 + 2
- A.
A = 24
- B.
A = 4
- C.
A = -16
- D.
A = 16
Correct Answer
D. A = 16Explanation
In the given equation, we have 6 on one side and a variable a divided by 4 plus 2 on the other side. To solve for a, we need to isolate it on one side of the equation. By subtracting 2 from both sides of the equation, we get a/4 = 4. Then, by multiplying both sides of the equation by 4, we find that a = 16.Rate this question:

9x − 7 = −7
- A.
X = 0
- B.
X = 1
- C.
X = 49
- D.
X =-63
Correct Answer
A. X = 0Explanation
The equation states that 9 times x minus 7 is equal to -7. To solve for x, we need to isolate it on one side of the equation. Adding 7 to both sides, we get 9x = 0. Finally, dividing both sides by 9, we find that x is equal to 0.Rate this question:

0 = 4 + n/5
- A.
N = -20
- B.
N = -1
- C.
N= 20
- D.
N = 0
Correct Answer
A. N = -20Explanation
By substituting -20 into the equation, we can verify if it satisfies the equation. Plugging in -20 for n, we get 0 = 4 + (-20/5), which simplifies to 0 = 4 - 4, giving us 0 = 0. Since the equation is true, n = -20 is the correct answer.Rate this question:

−1 = 5 + x/6
- A.
X = 4
- B.
X = -36
- C.
X = -6
- D.
X = 30
Correct Answer
B. X = -36Explanation
The equation given is −1 = 5 + x/6. To solve for x, we need to isolate it on one side of the equation. We can start by subtracting 5 from both sides, which gives us -6 = x/6. To further isolate x, we can multiply both sides by 6, resulting in -36 = x. Therefore, the correct answer is x = -36.Rate this question:

−9x + 1 = −80
- A.
X = -81
- B.
X = -9
- C.
X = 9
- D.
X = 0
Correct Answer
C. X = 9Explanation
The equation -9x + 1 = -80 can be solved by isolating the variable x. By subtracting 1 from both sides of the equation, we get -9x = -81. Dividing both sides by -9, we find that x = 9.Rate this question:

−10 = −10 + 7m
- A.
M = 1
- B.
M = 0
- C.
M = -70
- D.
M = -1
Correct Answer
B. M = 0Explanation
The equation given is −10 = −10 + 7m. To solve for m, we need to isolate the variable. By subtracting -10 from both sides of the equation, we get 0 = 7m. Dividing both sides by 7, we find that m = 0.Rate this question:

144 = −12x - 60
- A.
X = -12
- B.
X = 5
- C.
X = - 5
- D.
X = -17
Correct Answer
D. X = -17Explanation
The given equation is 144 = -12x - 60. To solve for x, we need to isolate the variable. By adding 60 to both sides of the equation, we get 204 = -12x. Dividing both sides by -12, we find that x = -17.Rate this question:

8n + 7 = 31
- A.
N = -2
- B.
N = 4
- C.
N = 1
- D.
N = 3
Correct Answer
D. N = 3Explanation
To solve the equation 8n + 7 = 31, we need to isolate the variable n. First, we subtract 7 from both sides of the equation to get 8n = 24. Then, we divide both sides by 8 to solve for n, which gives us n = 3. Therefore, the correct answer is n = 3.Rate this question:

M/9 − 1 = −2
- A.
M = -1/3
- B.
M = 27
- C.
M = 9
- D.
M = -9
Correct Answer
D. M = -9Explanation
The given equation m/9 - 1 = -2 can be solved by isolating the variable m. By adding 1 to both sides of the equation, we get m/9 = -1. Then, multiplying both sides by 9, we find that m = -9.Rate this question:
