Given the statement:
-78 is greater than or equal to - 8 + 5n
Solution:
The given statement can be written as,
-78 ≥ -8 + 5n
In order to solve for the inequality, we solve for n. To do so, transpose -8 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
-78 ≥ -8 + 5n
-78 + 8 ≥ 5n
-70 ≥ 5n
Divide both sides by 5 in order to determine the value of n.
-70/5 ≥ 5n/5
-14 ≥ n
Final answer:
-14 ≥ n
