Answer:
X= - 44
18x+3x+4-5=5(4x9
Collect like terms
21x+4-5=5(4x-9
More variable to the left hand side and change its sign
21x-20x-1=-45
Correct like terms
X=-45+1
Which is x=-44
Answer:
A) 100 x (4/5)
Step-by-step explanation:
Spent a total of 100 dollars, all being the same price
Each is 20 dollars.
For 4 pairs it would be 80.
100 x (4/5) = 80
A= B+C
As given, A+B+C = 50000 seats
A+(B+C) = 50000
2A = 50000
A= 25000 seats
Now section A sells seats at $30 each
So, 
Now, B+C = 25000
B = 25000-C
B sells at $24 and C sells at $18
So, 24B+18C = 538800
Now as section A incurs an amount of $750000 from booking, so B and C will incur 1288800-750000 = 538800 where $1288800 is the total booking amount.
24B+18C = 538800


6C = 61200
C = 10200
Now, B = 25000-C
B = 25000 - 10200 = 14800
Hence, section A has 25000 seats
Section B has 14800 seats
Section C has 10200 seats
Answer:
j=-2
Step-by-step explanation:
42j+18-19j=-28
Combine like terms
23j +18=-28
Subtract 18 from each side
23j +18-18 = -28 -18
23j =-46
Divide each side by 23
23j/23 = -46/23
j = -2
