Answer:
(1, 2 )
Step-by-step explanation:
Given the 2 equations
- 2x - y = - 4 → (1)
x + 2y = 5 → (2)
Multiplying (2) by 2 and adding result to (1) will eliminate x- term
2x + 4y = 10 → (3)
Add (1) and (3) term by term to eliminate x
0 + 3y = 6
3y = 6 ( divide both sides by 3 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (2)
x + 2(2) = 5
x + 4 = 5 ( subtract 4 from both sides )
x = 1
solution is (1, 2 )
This means that 2n is equal to or greater than -1 +10 or -1-10, which can be shown as 2n ≥ 9 and 2n ≥-11, and since 2n ≥11 encompasses both, we can therefore say 2n ≥-11 or n ≥ -5.5 by dividing both sides by 2
Answer:
either negative or positive integer
