To solve for x in the equation 811(x+45) = 2455, we first need to distribute the 811 to both terms inside the parentheses:
811x + 811(45) = 2455
811x + 36595 = 2455
Now, we need to isolate the x term by subtracting 36595 from both sides of the equation:
811x + 36595 - 36595 = 2455 - 36595
811x = -34140
Now, divide both sides by 811 to solve for x:
x = -34140 / 811
x โ -42.11
Therefore, the value of x is approximately -42.11.
