The answer is nine. Seriously. Here is my work if you don't believe me: 68=8x+23+4x-7x 68=8x-7x+23+4x 68=x+23+4x 68=x+4x+23 68=5x+23 68-23=5x 45=5x x=45/5 x=9
7y+ 8x + 4= 20 + 8x- 8x - 8x7y + 4 = 20- 4 - 47y=16/7 /7y= 2.28the /7 means divide by 7 :)
When simplified it is: 1-8x
8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
It is 8x + 16

7y+ 8x + 4= 20 + 8x- 8x - 8x7y + 4 = 20- 4 - 47y=16/7 /7y= 2.28the /7 means divide by 7 :)
The expression simplifies to -8x.
16x + 3
When simplified it is: 1-8x
- 8x + 8x = 0 so question is meaningless.
8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
4 + 8x
-8x - 10 - 20 = -8x - 30
8x-7+4 = 8x-3 simplified
It is: 8x^2 +68x +32
It is 8x + 16
