Answer:
Part a) 3.5 weeks
Part b) 185 tickets
Step-by-step explanation:
Part a) After how much time have the same number of tickets been sold for both festivals?
Let
x -----> the number of weeks
y ----> the number of tickets sold
we have
<em>Country Music Festival</em>
----> equation A
<em>Pop Music Festival</em>
----> equation B
Equate equation A and equation B
solve for x
Part b) What is the number of tickets sold at that time?
substitute the value of x=3.5 weeks in the linear equation A or linear equation B
Answer:
<h2>x = -7 and y=8</h2>
Step-by-step explanation:
<h2> soln</h2><h2>using by elimination method</h2><h2> 1|x+2y=9</h2><h2> 1| x+y=1</h2><h2> |x+2y=9</h2><h2> -|x+y=1</h2><h2> x-x+2y-y=9-1</h2><h2> 0+y=8</h2><h2> y=8</h2>
<h2> 1|x+2y=9</h2><h2> 2|x+y=1</h2>
<h2> |x+2y=9</h2><h2> -|2x+2y=2</h2>
<h2>x-2x+2y+2y=9-2</h2>
<h2>-x=7</h2><h2>divide -1 both side with the make value of x</h2><h2>x=-7</h2><h2>therefore x=-7 and y=8. this is my answer</h2>
