Answer 3

To solve the equation 3x = 51 + 18x, we'll first simplify the equation and then isolate the variable x. Here's the step-by-step solution:

1. Distribute the multiplication: 3x = 51 + 18x

2. Move all terms containing x to one side by subtracting 18x from both sides: 3x - 18x = 51

This simplifies to: -15x = 51

3. Divide both sides of the equation by -15 to solve for x: (-15x) / -15 = 51 / -15

Simplifying further: x = -51/15

The final solution is x = -3.4 (rounded to one decimal place).
