Answer:
The number of Integers satisfying 3|n| +2 <= 17 is 11.
Step-by-step explanation:
The solution set is: {-5,-4,-3,-2,-1,0,1,2,3,4,5}, which contains 11 elements.
11
3|n| + 2 <= 17 subtract 2 by both sides
3|n| <= 15 divide both sides by 3
|n| <= 5
Because it is absolute value negative and positive numbers and 0 fulfill this
So the answer would be 11 because -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5.

x = 2, y= 3
y = -2x+7
y = 5x-7
Since the equations are both equal to y, set them equal to each other
-2x+7 = 5x-7
Add 2x to each side
-2x+7 +2x= 5x+2x-7
7 = 7x -7
Add 7 to each side
7+7 = 7x
14 = 7x
Divide by 7
14/7 = 7x/7
2 = x
Now find y
y = 5*2 -7
y = 10-7
y =3
x=-17
x+54=37
-54. -54
