To solve the equation 3(5+2x)+4=1455 for x, follow these steps:
- Start by simplifying the expression inside the parentheses: 5+2x.
- Distribute the 3 to both the 5 and the 2x: 35 + 32x. This gives us 15 + 6x.
- Rewrite the equation with the simplified expression: 15 + 6x + 4 = 1455.
- Combine like terms on the left side of the equation: 15 + 4 + 6x = 1455.
- Simplify further: 19 + 6x = 1455.
- Subtract 19 from both sides of the equation: 6x = 1455 - 19.
- Simplify: 6x = 1436.
- Divide both sides by 6 to solve for x: x = 1436/6.
- Divide to get your final answer: x ≈ 239.33.
Therefore, x is approximately 239.33.
