X + 5y - 10 = 0
x = 2y - 8
Substitute the value of x in the 2nd equation to the 1st equation.
2y - 8 + 5y - 10 = 0
7y - 18 = 0 This is the resulting equation in its simplest form.
Find the value of y to get the corresponding value of x.
7y -18 = 0
7y = 18
y = 18/7
y = 2 4/7
x = 2y - 8
x = 2 (18/7) - 8
x = 36/7 - 8
x = 36/7 - (8 * 7/7)
x = 36/7 - 56/7
x = (36-56)/7
x = -20/7
x = -2 6/7
to check:
x + 5y - 10 = 0
-20/7 + 5(18/7) - 10 = 0
-20/7 + 90/7 - 10 = 0
-20/7 + 90/7 - (10 * 7/7) = 0
-20/7 + 90/7 - 70/7 = 0
(-20+90-70)/7 = 0
0/7 = 0
0=0

Answer:
- Set A = { 5, 25, 15, 35 }
- the set of multiples of 5
Step-by-step explanation:
Words to describe the set:
A set can also be described by just defining it using plain words. For example, the set A= {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday} can be described using words like “the set of days of the week”. Another example can be “the set of months of the year”.
(I) The 15 represents the money earned for each ticket sold
In other words the 15 is the cost of each ticket.
(II) The 700 represents the costs inquired when organizing the dance
In other words...how much it costs to throw the dance.
<u>Explanation</u>
Since t is the number of tickets and the function shows profit we know that every step on the left has some aspect to do with the profit....for ever ticket (t) sold there is an addition of 15 dollars...or for every 1 ticket sold $15 is earned....or each ticket costs 15 dollars
The -700 shows that 700 dollars must be subtracted from the total income from selling tickets....since this is looking for profit which is income-costs and we have already determined that 15t represents the income we know that the 700 must represent the costs of throwing the dance.
