Step-by-step explanation:
Move all terms that do not contain nn from the middle section of the inequality.
−5 <n≤2 - 5 <n≤2
Answer:
- 4, - 3, - 2, - 1, 0, 1, 2
Given
- 15 < 3n ≤ 6 ( divide the 3 intervals by 3
- 5 < n ≤ 2
Thus n can have values from - 4 to 2, that is
Expand the squared binomials:
Then
A) 5x-6y=3
B) 7y=2x+8
B) -2x + 7y = 8 then multiplying "B" by 2.5
B) -5x +17.5y = 20 then adding this to A
A) 5x -6y = 3
11.5y = 23
y = 2
x = 3
