Determine the number of solutions of the linear system: 14x + 7y = 315 16x - 2y = 610

1 answer:

5 0

14x + 7y = 315 reduces to 2x + y = 45
16x - 2y = 610 reduces to 8x - y = 305

2x + y = 45
8x - y = 305
----------------add
10x = 350
x = 350/10
x = 35
I didn't figure y because it is not needed to determine the number of solutions
I can tell u right now it will have 1 solution

mr_godi [17]

Each successive term is -5 times the previous one, so the underlying sequence is

$a_n=-5a_{n-1}=(-5)^2a_{n-2}=(-5)^3a_{n-3}=\cdots=(-5)^{n-1}a_1=8(-5)^{n-1}$

The sum can then be written as

$8-40+200-1000+\cdots=\displaystyle\sum_{n=1}^\infty8(-5)^{n-1}$

Answer: (7 + d) 4 and 4 (7 + d)

Step-by-step explanation:

4 (d + 7) = 4d + 28
