In each algebraic expression solve for x.

• 1.

### 2x = 10

• A.

X = 3

• B.

X = 19

• C.

X = 5

• D.

X = -7

C. X = 5
Explanation
To find the value of x, we need to solve the equation 2x = 10. By dividing both sides of the equation by 2, we get x = 5. Therefore, the correct answer is x = 5.

### 1/2x = 9

• A.

X = 18

• B.

X = 11

• C.

X = -9

• D.

X = 27

A. X = 18
Explanation
To solve the equation 1/2x = 9, we can multiply both sides of the equation by 2 to eliminate the fraction. This gives us x = 18. Therefore, the correct answer is x = 18.

Rate this question:

• 3.

### -2 + x = -27

• A.

X = 17

• B.

X = -25

• C.

X = 4

• D.

X = 15

B. X = -25
Explanation
To solve the equation -2 + x = -27, we need to isolate the variable x. To do this, we can add 2 to both sides of the equation. This will give us x = -25. Therefore, the correct answer is x = -25.

Rate this question:

• 4.

### -x - 11 = 4x = -15

• A.

True

• B.

False

A. True
Explanation
The given equation is -x - 11 = 4x = -15, which is not a valid equation as it contains two equal signs. Therefore, the correct answer cannot be determined based on the given information.

Rate this question:

• 5.

### -3/4x = 15 x = 20

• A.

True

• B.

False

A. True
Explanation
The given equation is -3/4x = 15. To solve for x, we need to isolate x on one side of the equation. To do this, we can multiply both sides of the equation by -4/3. This will cancel out the -3/4 coefficient on x, leaving us with x = -4/3 * 15. Simplifying this, we get x = -20. Therefore, the statement x = 20 is false.

Rate this question:

• 6.

### 3 (2 + x) = 0x = 2

• A.

True

• B.

False

B. False
Explanation
The given equation is 3(2 + x) = 0x = 2. However, this equation is not mathematically valid as it contains two equal signs, which is not allowed. Therefore, the correct answer is False.
