the way you typed it...

multiply each side by -2

(-2)(-1/2)x = -2(-3/4)

x = 3/2

"can you check if i have this one right 0.6x+2=1.4x-1

my answer is ≥ 3.75 im i correct"

You have correctly solved the equation to get x=3/0.8 = 3.75.

However your statement of x≥3.75 would be incorrect since the question given is an equation, and not an inequality.
