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

To solve the equation 3(5+2x) + 4 = 1455, we will first simplify the expression inside the parentheses.

We have: 3(5+2x) + 4 = 1455 Simplifying the expression inside the parentheses: 15 + 6x + 4 = 1455

Combining like terms: 19 + 6x = 1455

Next, we will isolate the variable x by subtracting 19 from both sides:

6x = 1455 - 19 6x = 1436

Finally, to solve for x, we divide both sides of the equation by 6:

x = 1436 / 6

x ≈ 239.33
