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

To solve the equation 3(5+2x) + 4 = 1455, we need to simplify and isolate the variable x.

First, distribute the 3 to both terms inside the parentheses: 15 + 6x + 4 = 1455

Combine like terms: 6x + 19 = 1455

Next, isolate the variable x by subtracting 19 from both sides of the equation: 6x = 1455 - 19 6x = 1436

Finally, to solve for x, divide both sides of the equation by 6: x = 1436 / 6 x = 239
