Question

Solve 5(n-2)=-30 check your solution

Answer 1

• n = -4

Step-by-step Solution:

• 5(n - 2) = -30
• => 5n - 10 = -30
• => 5n = -30 + 10
• => 5n = -20
• => n = -4

Check:

• 5(n - 2) = -30
• => 5(-4 - 2) = -30
• => 5(-6) = -30
• => -30 = -30

Hence, this is correct.

Answer 2

n>=-4

Explanation:

(0 - 5 • (n - 2)) - 30 ≤ 0

-5n - 20 = -5 • (n + 4)

-5 • (n + 4) ≤ 0

Divide both sides by -5

Subtract 4 from both sides which is n ≥ -4
