Identify the two inequalities given in the compound inequality: \(2x - 3 \leq 1\) and \(-x + 4 \leq 10\).
Solve the first inequality \(2x - 3 \leq 1\) by isolating \(x\): add 3 to both sides to get \(2x \leq 4\), then divide both sides by 2 to find \(x \leq 2\).
Solve the second inequality \(-x + 4 \leq 10\) by isolating \(x\): subtract 4 from both sides to get \(-x \leq 6\), then multiply both sides by \(-1\) (remember to reverse the inequality sign) to get \(x \geq -6\).
Since the compound inequality uses "or", the solution is all values of \(x\) that satisfy either \(x \leq 2\) or \(x \geq -6\).
Combine the solution sets: \(x \leq 2\) includes all numbers less than or equal to 2, and \(x \geq -6\) includes all numbers greater than or equal to -6. Together, these cover all real numbers, so the solution in interval notation is \((-\infty, \infty)\).
