Start with the given inequality: \$7x + 3 < 2x + 13$.
Use the subtraction property of inequality to get all the \(x\) terms on one side. Subtract \$2x\( from both sides: \)7x - 2x + 3 < 2x - 2x + 13\(, which simplifies to \)5x + 3 < 13$.
Next, use the subtraction property again to isolate the term with \(x\). Subtract \$3\( from both sides: \)5x + 3 - 3 < 13 - 3\(, which simplifies to \)5x < 10$.
Now, use the division property of inequality to solve for \(x\). Divide both sides by \$5\(: \)\frac{5x}{5} < \frac{10}{5}\(, which simplifies to \)x < 2$.
The solution to the inequality is \(x < 2\), meaning all values of \(x\) less than \$2$ satisfy the original inequality.
