To solve linear inequalities, treat them like equations, but remember to reverse the inequality sign if you multiply or divide both sides by a negative number.
Step 1: Subtract \(7x\) from both sides.
\[
8x + 4<7x + 8
\]
\[
8x - 7x + 4<8
\]
\[
x + 4<8
\]
Step 2: Subtract 4 from both sides.
\[
x<4
\]
Final Answer:
The solution to the inequality is \( \boxed{x<4} \).
