### 6 = a/4 + 2

• A.

A = 24

• B.

A = 4

• C.

A = -16

• D.

A = 16

D. A = 16
Explanation
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.

### 9x − 7 = −7

• A.

X = 0

• B.

X = 1

• C.

X = 49

• D.

X =-63

A. X = 0
Explanation
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.

### 0 = 4 + n/5

• A.

N = -20

• B.

N = -1

• C.

N= 20

• D.

N = 0

A. N = -20
Explanation
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.

### −1 = 5 + x/6

• A.

X = 4

• B.

X = -36

• C.

X = -6

• D.

X = 30

B. X = -36
Explanation
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.

### −9x + 1 = −80

• A.

X = -81

• B.

X = -9

• C.

X = 9

• D.

X = 0

C. X = 9
Explanation
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.

### −10 = −10 + 7m

• A.

M = 1

• B.

M = 0

• C.

M = -70

• D.

M = -1

B. M = 0
Explanation
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.

### 144 = −12x - 60

• A.

X = -12

• B.

X = 5

• C.

X = - 5

• D.

X = -17

D. X = -17
Explanation
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.

### 8n + 7 = 31

• A.

N = -2

• B.

N = 4

• C.

N = 1

• D.

N = 3

D. N = 3
Explanation
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:

• 10.

### M/9 − 1 = −2

• A.

M = -1/3

• B.

M = 27

• C.

M = 9

• D.

M = -9

D. M = -9
Explanation
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.
