1. **Problem 1: Simplify the expression** $3x + 5x - 2 + 4$. 2. **Step 1:** Combine like terms (terms with $x$ and constant terms separately). $$3x + 5x = 8x$$ $$-2 + 4 = 2$$ 3. **Step 2:** Write the simplified expression. $$8x + 2$$ 4. **Problem 2: Solve the linear equation** $2x + 3 = 11$. 5. **Step 1:** Subtract 3 from both sides to isolate the term with $x$. $$2x + 3 - \cancel{3} = 11 - \cancel{3}$$ $$2x = 8$$ 6. **Step 2:** Divide both sides by 2 to solve for $x$. $$\frac{2x}{\cancel{2}} = \frac{8}{\cancel{2}}$$ $$x = 4$$ This worksheet helps students practice combining like terms and solving simple linear equations step-by-step.
