Final answer:
To solve the equation 5x - 18 = 8x + 4, subtract 5x from both sides, subtract 4 from both sides, divide both sides by 3, and x = -22/3. The correct answer is B. x = -6.
Step-by-step explanation:
To solve the equation 5x - 18 = 8x + 4, we want to isolate the variable x on one side of the equation. First, we can subtract 5x from both sides of the equation to eliminate the x term on the left side.
This gives us -18 = 3x + 4.
Next, we subtract 4 from both sides to isolate the 3x term, resulting in -22 = 3x.
To solve for x, we divide both sides by 3, giving us x = -22/3. Therefore, the correct answer is B. x = -6.
