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

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

First, we'll simplify the expression inside the parentheses: 3(5+2x) + 4 = 1455 15 + 6x + 4 = 1455 19 + 6x = 1455

Next, we'll isolate the variable by subtracting 19 from both sides: 19 + 6x - 19 = 1455 - 19 6x = 1436

Then, divide both sides by 6 to solve for x: 6x/6 = 1436/6 x = 239

So the solution to the equation is x = 239.
