There is actually 2 ways to solve this, I will show you both.
The first is obvious, solve for x in the first one, and plug it into the 2nd one and get the answer
4x + 7 = 12
4x = 5
x = 
8() + 3
2 * 5 + 3
10 + 3
13
The 2nd option is to manipulate the 4x + 7 to be 8x + 3
4x + 7 = 12
start by moving the 7 over
4x = 5
multiply both sides by 2
8x = 10
and add 3 to both sides
8x + 3 = 13
No, that would not be reasonable to say.
If you were filling some buckets, you could say 4 gallons, but we’re talking about a bowl and at the most that will take just a few cups.
I hope this helps and please let me know if you need further explanation!

Answer:
3rd option
Step-by-step explanation:
Since the centre of dilatation is at the origin then multiply the coordinates by 
K (- 3, 9 ) → K' (- 3( ), 9( ) ) → K' (- 1, 3 )
L (- 9, 0 ) → L' (- 9( ), 0 ( ) ) → L' (- 3, 0 )
M (2, - 8 ) → M' (2 ( ), - 8 ( ) ) → M' ( 
, - 
)
N (6, 4 ) → N' (6 ( ) , 4 ( ) ) → N' ( 2, 
)
<span>(-5y^3 - 7y) + (7y^3 + 8y +9)
</span>
-5y^3+7y^3-7y+8y+9 <---- Group like terms
-5y^3+7y^3+y+9 <---- Add similar elements
Answer: 2y^3+y+9
Read it carefully as it may look confusing with the symbols.
