To solve this equation, we can combine like terms and then isolate the variable x.

X + x*1.5 + 1.5x + 110 = 310

First, simplify the terms involving x:

X + 2.5x + 110 = 310

Next, combine the X term and constant term on one side of the equation:

2.5x + X = 310 - 110
2.5x + X = 200

Combine the x terms:

3.5x = 200

Divide by 3.5 on both sides to isolate x:

x = 200 / 3.5
x = 57.14

Therefore, the value of x is 57.14.
