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

To solve this equation, substitute the value of x into the equation and simplify:

3(5 + 2*1455) + 4

First, calculate 2*1455 = 2910:

3(5 + 2910) + 4

Next, calculate (5 + 2910) = 2915:

3(2915) + 4

Finally, calculate 3*2915 = 8745:

8745 + 4 = 8749

Therefore, the solution to the equation 3(5+2x) + 4 when x = 1455 is 8749.
