So where do i start and what do i do?

first one is:
3x + y = 6
3x – y = 0

And the second one is:
x – y = 2
3x – 3y = 6


can anyone explain this to me a little....my teacher isn't very helpful!

Help - someone gave this puzzle to my 9 year old for a bit of fun to see if he can work it out - I've tried several times but don't seem to get anywhere................

A bath takes 5 minutes to fill with the plug in. It takes 8 minutes to empty when you take the plug out. How long does it take for the bath to fill with the plug out ?

Cheers
Andrew

Hi, i don't know how to do these 3 problems,please give me a help
1. Solve for x:
log 5 (5^2x) = 8

2. log x^3/2 - log (square root x) = 5

3. ln (1/x) + ln (2x^3) = ln 3

For number 1 the answer on the back of the book is 4,#2 is 10^5,and #3 is square root 3/2,i can't get any of those answers,please tell me how to get those answers.
Showing all the steps will be better for me to understand completely,thanks!!

Simplify

(-8y) + 3 + ( -X) + Y - ( -2X)

(X+1) ( -7 )

-6 (X-1)

(X+5)(-8)

-8(X+1)

25=5(X-4)

40=10(X+8)

1/6 ( 18X+18) = 12

Aspirin, C9H8O4, is produced from salicylic acid, C7H6O3, and acetic anhydride, C4H6O3, as shown below.

C7H6O3 + C4H6O3 C9H8O4 + HC2H3O2

(b) How much salicylic acid would be required if only 53% of the salicylic acid is converted to aspirin?

(c) What is the theoretical yield of aspirin if 159 kg of salicylic acid is allowed to react with 149 kg of acetic anhydride?

(d) If the situation described in part (c) produces 163 kg of aspirin, what is the percentage yield?
