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

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

First, let's distribute the 3 to the terms inside the parentheses: 3 * 5 + 3 * 2x + 4 = 1455 15 + 6x + 4 = 1455

Combine like terms: 6x + 19 = 1455

Next, subtract 19 from both sides of the equation: 6x = 1455 - 19 6x = 1436

Finally, divide both sides by 6 to solve for x: x = 1436 / 6 x ≈ 239.33

Therefore, the value of x that satisfies the equation is approximately 239.33.
