You can add another equation 

X+y = 7 

Let x be the number of General Admission tickets  

And Y be the number of Seat Reserved Seat tickets

the equation is 

4x +9y = 43 

Do you understand the first four questions ? 

Today was my last exam of the fall semester 

Now I've 3 weeks holiday 

1 -  multiply by - 3 

2 -  multiply by 3

3 - divude by 4  

4 -  divide by four 

Solve for K 

\(-3K=25-7-12\)

\(-3K = 6\)

\(K = \frac{6}{-3}\)

\(K =-2\)

You are welcome 

do you get it? 

Ok.

To open a square brackets follow this 

1 - square the first term    ( in this question the first term is " 3x " so \((3x)^2 = 3^2*x^2 = 9x^2 \)) 

2 - Multiply the power which is alwayse " 2 " with the two terms ( In this qestion \(2 * 3x * -3 = -18x \) ) 

3 - square the second term ( In this question the second term is " -3 " so \((-3)^2 = 9 \)

4 - gather your answer 

\((3x-3)^2 = 9x2 - 18x + 9 \)

\(\sum F = ma\)

\(a= \frac{\sum F}{m}\)

\(a = \frac{40}{40}\)

\(a = 1 \frac{m}{s^2}\)
