Explicación paso a paso:
To solve this equation, we need to combine like terms and isolate the variable x:
x + 2/5 - x - 1/2 = 3 - x/4 2/5 - 1/2 = 3 - x/4 2/5 - 10/20 = 3 - x/4 8/20 - 10/20 = 3 - x/4 -2/20 = 3 - x/4 -1/10 = 3 - x/4 -x/4 = -1/10 - 3 -x/4 = -31/10 -x = -124/10 x = 124/10 x = 12.4
Therefore, the solution to the equation is x = 12.4.
