Tom has a collection of 30 CDs and Nita has a collection of 18 CDs. Tom is adding 1 CD a month to his collection while Nita is adding 5 CDs a month to her collection. Find the number of months after which they will have the same number of CDs. A. 1 month B. 3 months C. 2 months D. 33 months
Weegy: equation to show work: 1x + 30 = ? 5x + 18 = ? x = the number of moths x = 3 User: What is the solution of the system?y = –3x + 2 y = –3x + 4 Weegy: 2(2x/3 + 7) - 3 = 5x 4x/3 + 14 - 3 = 5x 11 = 11x/3 x = 3 y = 2(3)/3 + 7 = 9 x(y) = 3(9) = 18. Answer is d. User: What is the solution of the system?y = x + 5 y = –5x – 1 Weegy: x=2 User: What is the solution of the system? Use substitution. y = x + 6 y = 2x A. (6, 12) B. ... (More)

y = x + 5
y = –5x – 1
institute y in the second equation the result is:
x + 5 = -5x - 1
x + 5x = -1 - 5
6x = -6
x = -1
y = -1 + 5 = 4
The solution for the system y = x + 5 y = –5x – 1 is (-1, 4)

3x – 4y = 9
–3x + 2y = 9
adding up equations the result is;
-2y = 18
y = -9
3x - 4(-9) = 9
3x + 36 = 9
3x = 9 - 36 = -27
x = -9
The solution for the system 3x – 4y = 9 –3x + 2y = 9 is (-9, -9)

y = –3x + 2 y = –3x + 4 A. no solutions B. (0, 2) C. infinitely many solutions D. (0, 4)
Weegy: C. infinitely many solutions User: What is the solution of the system? Use substitution. x = –2y + 10 –6y = 6x – 6 z = –3x + 10y A. x = 9, y = –8, z = 114 B. x = –8, y = 9, z = 114 C. x = –8, y = 114, z = 9 D. x = 114, y = 9, z = –8 Weegy: A. x = 9, y = ?8, z = 114 is the answer. User: How many solutions does the system have? x = -4y + 4 2x + 8y = 8 A. one solution B. two solutions C. infinitely many solutions D. ... (More)
