DONT TRUST THE GERMANS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
(a)x + y = 58 and x = y + 14
(b) You sold 36 and your friend sold 22.
Tickets that you sold = x
Tickets that your friend sold = y
Together, the two of you sold 58 tickets.
x + y = 58
You sold 14 more than your friend
x = y + 14
So the two equations are:
x + y = 58
x = y + 14
------------------------------------------------------------------------
Construct system of equations and solve for x and y
------------------------------------------------------------------------
x + y = 58 ------------ (1)
x = y + 14 -------------(2)
Substitute equation (2) into equation (1)
(y + 14) + y = 58
y + 14 + y = 58
2y + 14 = 58
2y = 58 - 14
2y = 44
y = 22 ---------------- Substitute into equation (2)
x = y + 14
x = 22 + 14
x = 36
------------------------------------------------------------------------
Find the tickets you and your friend sold
------------------------------------------------------------------------
you = x = 36
your friend = y = 22
------------------------------------------------------------------------
Answer: (a) x + y = 58 and x = y + 14
(b) You sold 36 and your friend sold 22.

Answer:
9. -4x+19y-7
10. 7x+20
Step-by-step explanation:
9. To simplify this expression, simply combine like terms. Add all of the terms with the x variable together, then the terms with the y variable, then the constant terms. I will show this step by step, but usually you do not have to show this work. The order of the terms does not matter.
x variable terms: (4x-8x)+7y-2+6y+6y-5= -4x+7y-2+6y+6y-5
y variable terms: (7y+6y+6y)-4x-2-5=19y-4x-2-5
constant terms: (-2-5)-4x+19y=-4x+19y-7
10. To simplify this expression, expand all terms and then combine like terms. The first term can be expanded by multiplying each term in the parentheses by 2.
Expand terms: 2(5+3x)+(x+10)= 10+6x+x+10
Now, you can combine like terms as done on the last problem. Note that I got rid of the parentheses in the second term, as they did not matter (since there was no term in front of them).
x variable terms: (6x+x)+10+10=7x+10+10
constant terms: (10+10)+7x=7x+20
