To solve the equation 3(5+2x) + 4 = 1455, follow these steps:
Start by expanding the expression inside the parentheses: 3(5+2x) + 4 = 3 * 5 + 3 * 2x + 4
Simplifying, we get: 15 + 6x + 4 = 1455
Combine like terms: 6x + 19 = 1455
Subtract 19 from both sides of the equation to isolate the variable: 6x = 1455 - 19
Simplifying: 6x = 1436
Divide both sides of the equation by 6 to solve for x: x = 1436 / 6
Simplifying: x = 239
