Answer 3

To solve the equation 5x + 15x - 3x = 510, you'll first want to combine like terms on the left side of the equation and then solve for x. Here's the step-by-step process:

1. Combine like terms on the left side of the equation: 5x + 15x - 3x = 510

   Combine the x terms: (5x + 15x - 3x) = 17x - 3x = 14x

2. Rewrite the equation with the combined terms: 14x = 510

3. Now, you can solve for x by isolating it on one side of the equation. To do this, divide both sides by 14: (14x) / 14 = 510 / 14

   Simplify: x = 510 / 14

4. Finally, simplify the right side of the equation: x = 36.43 (rounded to two decimal places)

So, the solution to the equation is approximately x = 36.43.
