Answer:
Explanation:
This is an inequality, not an equation. There will be a set of x-values for which the inequality will be true.
First eliminate the fractional coefficient 2/5 by multiplying all terms by 5:
25 < 2x + 15 ≤ 75
Subtracting 15 from each 5, (2/5)x, 3 and 15 yields:
22 < 2x ≤ 60
Dividing all three terms by 2, we get:
11 < x ≤ 30
Thus, any number greater than 11 but equal to or less than 30 is a solution.
