What is the simplest form of \\(11\leq 2x+1\\)?

Answer and explanation

Correct answer: \\(x\geq 5\\)

Subtracting 1 from both sides gives \\(10\leq 2x\\). Dividing both sides by the positive number 2 yields \\(5\leq x\\), which is equivalent to \\(x\geq 5\\). The inequality sign does not reverse when dividing by a positive number. Exam tip: Reverse the sign only when multiplying or dividing an inequality by a negative number.
