4x + 16 - x = 22 + 6

First group like terms 

4x - x + 16 = 22 + 6

3x + 16 = 22 + 6

Then add 22 + 6

3x + 16 = 28

Subtract 16 on both sides 

3x + 16 - 16 = 28 - 16

3x = 12 

Divide both sides by 3 

3x/3 = 12/3

x = 4

The answer is B:  x = 4

Hope this helps ;P

-8x + 4 = 36

Subract 4 on both sides 

-8x + 4 - 4 = 36 - 4

-8x = 32

Then divide both sides by -8

-8x/-8 = 32/-8

x = -4

So the answer is D: x = -4

Hope this helps ;P

Yes he added 15 to -20 to get -5. There are different ways to do this problems the Guests way or my way or another way.

4(2x -5) + 15 =11

Subtract 15 on both sides

4(2x- 5) =  - 4

Divide 4 on both sides

2x - 5 = -1

Add 5 on both sides

2x = 4

Divide both sides by 2 

X = 2

Hope this helps ;P

The answer is C) 103

7(6+2)2-3^2

(6+2) = 8

7*8*2-3^2

3^2 = 9

7*8*2-9

7*8*2 = 112

112 - 9

103

Hope this helps ;P

It might be my answer not my question that needs the heart. Idk
