Answer:

Step-by-step explanation:
So we have the equation:

And we want to solve for x. In other words, we want to isolate the x-variable.
So, add 2y to both sides of the equation.

On the left, the 2y cancel. Simplify the right:

And we're done!
Slope = (y2-y1)/(x2-x1)
(3+1)/(2-0) = 4/2 = 2
The slope is 2
Answer:
11a. 15x + 6
11b. x + 8 < 16 or x + 8 - 16
12. 3x + 15 + 5x = 8x + 15
13. 7x + 31
