To solve the inequality [tex]\(5 < 2x + 3\)[/tex], follow these steps:
Step 1: Subtract 3 from both sides of the inequality.
[tex]\[ 5 - 3 < 2x + 3 - 3 \][/tex]
This simplifies to:
[tex]\[ 2 < 2x \][/tex]
Step 2: Subtract [tex]\(2x\)[/tex] from both sides of the inequality.
[tex]\[ 2 - 2x < 0 \][/tex]
Step 3: Divide both sides of the inequality by the coefficient of [tex]\(x\)[/tex] (which is 2).
[tex]\[ \frac{2}{2} < \frac{2x}{2} \][/tex]
This simplifies to:
[tex]\[ 1 < x \][/tex]
Therefore, the missing step is:
[tex]\[ \boxed{\text{Subtract } 2x \text{ from both sides of the inequality.}} \][/tex]
