Answer: I got it to you fast no flash
The first given equation is:
j + k = 3
This can be rewritten as:
j = 3 - k .................> I
The second given equation is:
j - k = 7 ............> II
Substitute with I in II and solve as follows:
j - k = 7
(3-k) - k = 7
3 - 2k = 7
-2k = 7-3 = 4
k = 4/-2
k = -2
Substitute with k in I to get the value of J as follows:
j = 3 - k
j = 3 - (-2) = 3+2
j = 5
Based on the above, the solution is (5,-2)
First way : (1/3n) - 7 <= 95
Second way : 1/3 * n - 7 <= 95
<= (less than or equal to)
>= (more than or equal to)
