To solve this equation, first simplify the expression on the left side:

1-2(1,5-x) = 1 -3 + 2x = 2x - 2

1-4(x-2) = 1 - 4x + 8 = -4x + 9

Now we have the equation:

2x - 2 = -4x + 9

Add 4x to both sides:

6x - 2 = 9

Add 2 to both sides:

6x = 11

Divide by 6:

x = 11/6

Therefore, the solution to the equation is x = 11/6 or approximately x = 1.83.
