Answer:
The answer should be 420.
~
Step-by-step explanation:
2y+6x=0
-6x from both sides
2y=-6x+0
then divide by 2 to each side so it looks like this 2y/2=-6x+0/2
the 2 cancels 2y so you're left with y
Then divide -6/2=-3 and 0/2=0
y=-3x+0
Does that answer your question?
The answer would be 56n^2 + 19n - 15
Multiply 8n with 7n to get 56n^2, then multiple 8n with 5 and you get 40n, then multiple -3 with 7n to get -21n, then -3 times 5 which gives you -15. Simplify and that is the answer you would get.

For 44- 3x-14=2x+10. So x=24
For 45- 6x=90. So x=15
For 46- 7x+5=180. So x=2
I dont know 47. Sorry
