Linear Equation F5162B
1. **State the problem:** Solve the equation $$\frac{4x - 1}{2} = x + 7$$ for $x$.
2. **Formula and rules:** To solve linear equations, we aim to isolate $x$ on one side by performing inverse operations such as addition, subtraction, multiplication, and division.
3. **Step 1: Eliminate the denominator** by multiplying both sides by 2:
$$2 \times \frac{4x - 1}{2} = 2 \times (x + 7)$$
which simplifies to
$$4x - 1 = 2x + 14$$
4. **Step 2: Get all $x$ terms on one side and constants on the other:**
Subtract $2x$ from both sides:
$$4x - 2x - 1 = 14$$
which simplifies to
$$2x - 1 = 14$$
5. **Step 3: Isolate $x$:**
Add 1 to both sides:
$$2x = 15$$
6. **Step 4: Solve for $x$ by dividing both sides by 2:**
$$x = \frac{15}{2}$$
7. **Final answer:**
$$x = 7.5$$
This means the solution to the equation is $x = 7.5$.
