B/parallel lines. This is because:
equation a) y=-2x+6
equation b) 3y=-6x+18 or if you divide by 3 on both sides y=-2x+6 (so actually they're effectively the same line)
Answer: -5
Step-by-step explanation:
Multilpy
x (-5 + 5 x (3)
Calculate
x (-5 - 15)
-
x 20
= -5
Let
y------> the amounts (in liters) of yellow paint
b-----> the amounts (in liters) of blue paint
we know that

so

therefore
<u>the answer is</u>

The answer is option C. Both Friedrich and Jung have the most debt. Hope I could help! :D
1. Subtract 8 from both sides
2. Simplify to get x= -23
