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

To solve the equation, we'll substitute the value of x into the equation and simplify it.

Given equation: 3(5+2x) + 4 = 1455

Substituting x = 1455:

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

Using the order of operations (PEMDAS/BODMAS):

3(5 + 2910) + 4 = 1455

3(2915) + 4 = 1455

8730 + 4 = 1455

8734 = 1455

Since the equation is false (8734 is not equal to 1455), the value of x that was substituted is not the solution to the equation.
