Solve the inequality $-7 < 5x − 2 "; Represent the solution on a real number line.

To represent $-1 < x \le 1$ on a real number line, draw a number line. Place an open circle at $-1$ (because $x$ is strictly greater than $-1$). Place a closed circle (or a filled dot) at 1 (because $x$ is less than or equal to 1). Draw a line segment connecting these two circles, indicating that all numbers between $-1$ and 1 (including 1 but not $-1$) are part of the solution.
