Answer:
x= 8/5 - 4/5y
Step-by-step explanation:
To get x independent we need to get everything else on the side x is on to the other side. We can start by adding 4y to the other side. We add because its negative and negative and positive cancel each other out.
-5x-4y=-8
add 4y
-5x= - 8 + 4y
Then to get the negative 5 to the other side we divide it to cancel it because it is multiplying right now.
-5x= - 8 + 4y
divide -5
x= - 8/-5 +4/-5y
in the fraction -8/-5 the negatives cancel out to get 8/5 and for 4/-5y we can more the negative to get us our final answer which is x=8/5-4/5y
Answer: 6a²-a-35

Step-by-step explanation:
Answer:
This is about your opinion, not mine, but here's my opinion.
Don't copy and paste because anything can be found with good filters.
Essentially, just paraphrase or something.
Step-by-step explanation:
I prefer standard notation when calculating with small digits under 6 zeros because it is more visually simpler to view. When a number is involved with more digits, I prefer scientific notation because it is unlikely that I will lose track of how many digits there are.
8 x 107 = 856
2 x 104 = 208
856 - 208 = 648
