To find the solution set, we need to isolate the variable x by getting rid of the constant term on one side of the inequality.
−2x + 5 > 7
Subtract 5 from both sides:
−2x > 2
Now, divide both sides by −2, remembering to flip the inequality symbol because we are dividing by a negative number:
x < -1
Thus, the solution set is all real numbers less than -1.
