Answer:

3x–2x+8 = 10x+5

=> x + 8 = 10x + 5

=> 8 – 5 = 10x – x

=> 9x = 3

=> x = 3/9

=> x = 1/3

Answer:
d

Step-by-step explanation:

Slope intercept form: y = mx + b

y = -x + 7
x + y = 21

x + y = 21
-x -x
y = -x + 21

y = -x + 7
y = -x + 21

Parallel lines have the same slope. Here, our slope is -1

Therefore, our final answer is d.

Hope this helps!
