### 7x-11+7x+11

• A.

11x

• B.

14x

• C.

5x

• D.

8x

B. 14x
Explanation
The given expression is 7x - 11 + 7x + 11. By combining like terms, we can simplify it to 14x. The coefficients of the x terms (7x and 7x) add up to 14x, while the constants (-11 and 11) cancel each other out. Therefore, the simplified expression is 14x.

### 5x+2-3x

• A.

2x+2

• B.

2

• C.

-2

• D.

1

A. 2x+2
Explanation
The given expression is 5x+2-3x. To simplify this expression, we combine like terms. The x terms, 5x and -3x, can be added together to give 2x. The constant terms, 2 and 0, can be added together to give 2. Therefore, the simplified expression is 2x+2.

### -3y-3+6x+3y-10

• A.

16x-13

• B.

10x-3

• C.

2x+10

• D.

None

D. None
Explanation
The given expression -3y-3+6x+3y-10 simplifies to 6x-13. None of the given answer choices match this simplified expression. Therefore, the correct answer is "None".

### 4x-x

• A.

None

• B.

3x

• C.

2

• D.

X

B. 3x
Explanation
The expression 4x - x can be simplified by subtracting x from 4x, which gives us 3x. Therefore, the correct answer is 3x.

### 7a + 8 - 3a

• A.

4a+8

• B.

15a+3a

• C.

7a+8

• D.

8a+5a

A. 4a+8
Explanation
The expression 7a + 8 - 3a simplifies to 4a + 8. This is because when we combine like terms, we add the coefficients of the same variable. Here, the coefficients of 'a' are 7 and -3. So, when we subtract 3a from 7a, we get 4a. The constant term 8 remains unchanged. Therefore, the simplified expression is 4a + 8.

### 3x +4x?

• A.

10x

• B.

7x

• C.

8x

• D.

None

B. 7x
Explanation
The given expression is 3x + 4x. To simplify this expression, we can combine the like terms, which in this case are the terms with the variable x. Adding 3x and 4x gives us a total of 7x. Therefore, the correct answer is 7x.

### Combine the like terms. 8y + 5y

• A.

8y

• B.

10y

• C.

13y

• D.

15y

C. 13y
Explanation
When combining like terms, we add the coefficients of the terms with the same variable. In this case, we have 8y and 5y. Adding the coefficients 8 and 5 gives us 13. Therefore, the answer is 13y.

### 16-3x+2-5y+10x

• A.

7x-5y+18

• B.

2x+2

• C.

17x+3

• D.

None

A. 7x-5y+18
Explanation
The given expression can be simplified by combining like terms. We can combine the terms with 'x' and the terms with 'y'. Combining the terms with 'x', we get -3x + 10x = 7x. Combining the terms with 'y', we get -5y. The constant terms 16 and 2 can be combined to give 18. Therefore, the simplified expression is 7x - 5y + 18.

### -20x+x-12+3y-6-7x

• A.

15

• B.

12x+y

• C.

-25x+2y-18

• D.

-26x+3y-18

A. 15
Explanation
The given expression is simplified by combining like terms. By combining the terms -20x and -7x, we get -27x. Similarly, combining x and 3y, we get 4y. Combining -12, -6, and 15, we get -3. Therefore, the simplified expression is -27x + 4y - 3. However, this does not match any of the given answer choices. Therefore, the correct answer is not provided.

### 15y+27-15y-20-7

• A.

7x-11

• B.

1

• C.

0

• D.

12

C. 0
Explanation
The given expression is 15y + 27 - 15y - 20 - 7. Simplifying this expression, we can combine like terms. The 15y and -15y cancel each other out, leaving us with 27 - 20 - 7. Simplifying further, we get 7 - 7, which equals 0. Therefore, the correct answer is 0.
