3(5+2x)+4 x=1455

To solve the equation 3(5+2x) + 4 = 1455 for x, follow these steps:

1. Distribute the 3 to both terms inside the parentheses: 15 + 6x + 4 = 1455

2. Combine like terms: 6x + 19 = 1455

3. Subtract 19 from both sides of the equation: 6x = 1455 - 19 6x = 1436

4. Divide both sides by 6: x = 1436/6 x = 239

So, the solution to the equation is x = 239.
