This equation can be solved by first simplifying both sides of the equation and then isolating the variable x.

Expanding the left side
3(2x) + 15.5(2x-1) = 8 + 15
6x + 31x - 15.5 = 8 + 15
37x - 15.5 = 8 + 15x

Combine like terms
37x - 15.5 = 8 + 15
37x - 15.5 - 15x =
22x - 15.5 = 8

Add 15.5 to both sides
22x - 15.5 + 15.5 = 8 + 15.
22x = 23.5

Divide by 22 to isolate x
x = 23.5 / 2
x ≈ 1.0682

Therefore, the solution to the equation is x ≈ 1.0682.
